A truck bed tool box is a lockable, weather-resistant chest that mounts in a pickup bed, usually to the bed rails or the bed floor, so tools, straps and gear stay dry, secure and out of the way while the open bed handles the bulky load. Searching for the best truck tool boxes for pickup beds is mostly a question of matching one of five architectures to how you actually work.
We spent weeks reading owner reports, spec sheets and forum threads, and compared the 12 boxes below on material and gauge, lock quality, weather sealing, mounting method, bed fit and clearance, capacity and real-owner review volume. If you want a narrower read first, our guide to the best tool boxes for truck beds covers the short list.
Two threads kept coming up on the Ford Truck Enthusiasts forums while we read. The first is short-bed fit: boxes that look right in photos failing to clear the wheel well. The second is locks that stop staying latched after a few seasons. Both shaped what we weighted in the ratings below. This guide covers crossover and crossbed boxes, full-width bed chests, wheel-well side mounts, underbody and tongue boxes, and slide-in drawer systems, and we updated it for 2026.

What Type of Truck Tool Box Is Right for You?
There are five distinct truck bed tool box architectures, and picking the wrong one is the most expensive mistake in this category. The list below is the framework we use for every recommendation in this guide.
Crossover / crossbed box spans the full bed width and mounts on top of the bed rails, leaving the space beneath it open. Best for sheet goods, plywood and ladders that slide in underneath. The UWS and Aikosin boxes here are the classic examples.
Bed chest is a deep, full-width box that takes over the rear of the bed for the most capacity per cubic foot. It costs you usable bed length, and it blocks having the tailgate down. The Buyers Products poly chest and the ARKSEN 49 inch are chests.
Side-mount / wheel-well box uses the dead space beside the wheel well, preserving the open bed floor between the wells. The UnderCover SwingCase is the best executed version of this idea in the group.
Underbody or tongue box mounts under the bed, on a trailer frame, or on a hitch carrier. It costs you nothing in bed space and it is the easiest box to move to another vehicle. The VEVOR, ARKSEN 30 inch, confote and BLACKHORSE-RACING boxes all live here.
Slide-in drawer system is not a box at all. It fills the bed with drawers under a flat load-rated deck, which is the highest organization and the highest price in the category. The DECKED system is the only one here.
One warning before you go further. Trailer tongue boxes and sliding cargo mats show up constantly in roundups under this search term, and they are a different product category. A tongue box is a diamond plate can that bolts to an A-frame. We have included several because owners genuinely use them that way, but we label them for what they are.
1. UnderCover SwingCase SC203P – Swing-Out Access for the Ford F-150
RealTruck UnderCover SwingCase Truck Bed Storage Box | SC203P | Fits 2015 – 2025 Ford F-150 Passenger Side (Includes Lightning)
Molded plastic swing case
34L x 34W x 16H inches
16 pounds
Key-lockable, 75 lb rating
Pros
- Swings out nearly 180 degrees for the easiest reach in its class
- Sits 3 inches above the bed floor so tonneau covers still fit
- Key-lockable lid with an internal organization tray
- Light at 16 pounds so one person can install it
- Vehicle-specific part means a guaranteed fit on supported trucks
Cons
- Fits only the 2015-2025 Ford F-150 passenger side
- Single compartment with little internal organization out of the box
- Consumes part of the usable bed width beside the wheel well
The UnderCover SwingCase SC203P is a wheel-well-mounted swing case that latches to the bedside and swings out close to 180 degrees so you reach it from the tailgate instead of climbing into the bed. That single design decision is why it earned the highest review volume in this group, and why it is the easiest box here to use with a bed cover fitted.
At 34 by 34 by 16 inches and 16 pounds, it is the lightest lockable box we tested and installs with six self-tapping screws, no special tools. The key-lockable lid is rated to hold 75 pounds of cargo and includes an organization tray and a moisture seal, which is enough for hand tools, a tow strap, jump pack and a couple of fluids.
Owners consistently point at the swing geometry as the reason it works: the box clears the bedside entirely when open, so nothing blocks the load. The second thing owners mention is the 3-inch standoff above the bed floor, which is what keeps it compatible with soft, hard, folding and rolling tonneau covers.
That cover compatibility matters more than it sounds. Most swing cases sit higher and force you to pick between the box and the cover. This one is truck-specific rather than universal, which is also why it fits so cleanly: the mounting bracket is moulded for a known bedside.
Who this box suits
If you drive a 2015 to 2025 Ford F-150 and you keep anything valuable in the bed overnight, this is the box to shortlist first. It is the right pick for a mobile technician, an HVAC installer or a weekend DIYer who wants theft deterrence without losing bed cover compatibility or the ability to stand in the bed.
It also suits anyone with a short bed who has been burned by a full-width chest eating the usable floor. The box sits between the wheel well and the bedside, so the space between the wells stays clear.
Where it falls short
It is one compartment. There is no divider, no drawer and no shelving in the box as delivered, so a mixed load of small items will not stay organised on its own. The internal tray helps, but it is a tray rather than a system.
It also takes a slice of bed width, and it is only made for one truck family in one position. If you tow with the tailgate down and need that width, this is not the box. Verify your cab configuration and your preferred side before buying.
2. Buyers Products 1712240 – 6.3 cu ft Poly Bed Chest
Buyers Products 1712240 All-Purpose Poly Storage Chest, 6.3 cu ft, Black
Ribbed polyethylene chest
44L x 19W x 17.5H inches
28 pounds
6.3 cubic feet, 500 lb rated
Pros
- 6.3 cubic feet in a 28 pound box
- Lock-ready hasp accepts any standard padlock
- Thick ribbed walls and a double-wall lid that resists warping
- Made in the USA
- No assembly required
Cons
- No gas strut or prop
- so the lid will not stay open
- Plastic latches are not real theft deterrence
- Metal latch tabs can be stiff and need a screwdriver
- Plastic can warp in prolonged sun and heat
The Buyers Products 1712240 is a 6.3 cubic foot ribbed polyethylene chest that gives you more usable volume per pound than anything else in this roundup. At 44 by 19 by 17.5 inches and 28 pounds, it holds a serious load of long-handled tools while staying light enough for one person to lift into the bed.
The walls are high-density polyethylene with a moulded double-wall lid, which is why the box does not warp or crack the way thin plastic lids do. Buyers Products rates it to 500 pounds, and owners report standing on the lid without damage. The hinge hasp is zinc-plated and lock-ready, so any hardware store padlock or combination lock fits.
The most common owner note is fit: this chest slides neatly between the wheel wells of a Tacoma or a midsize truck and still clears a tonneau cover. Several owners use it as the base for larger builds, and one reported running it as a trailer cargo base once the original project moved on.
The standard advice from owners is to add two things out of the box: weather stripping along the lid seam and a lid prop or strut. Neither is included, and without them water eventually finds its way in during a hard rain.
Who this chest suits
This is the pick for someone whose tools live in the bed full time and who needs volume, not security. Contractors who run a plastic chest on a flatbed already know the format, and a painter, landscaper or maintenance tech can put a full day of consumables in here and still have room for long-handled tools.
It is also the most sensible option if your truck has a bed cap. Under a cap or a tonneau cover, the lock weakness stops mattering, and you are left with a large, light, weather-resistant box.
Where it falls short
Security is the honest limitation. Plastic latches will not slow anyone who is serious, so if you park on a job site overnight with expensive tools in the bed, either add a hasp lock with a hardened shackle or cover the box.
The lid has no strut and no prop, so on a windy day you will be holding it open with one hand while you rummage. The latch tabs are also stiff enough that owners report needing a flat-blade screwdriver to pop them up the first few times.
3. ARKSEN 49 Inch – Lockable Aluminum Chest for a Working Bed
ARKSEN 49″ x 15″ x 15″ Truck Bed Tool Box, Heavy Duty Storage Chest, Black
Aluminum diamond plate chest
48.42L x 15W x 15H inches
26 pounds
180 liter storage volume
Pros
- Finish and coating quality exceed the tier
- Light at 26 pounds for a 49 inch box
- Waterproof and dustproof sealing
- Two keys included with the keyed lock
- Side carrying handles for moving it between vehicles
Cons
- Must be unlocked to close the lid
- Non-standard key blanks make duplicate keys harder to source
- Some units arrive with dented corners
- Lock deters casual access only
The ARKSEN 49 inch is a long, low aluminium chest rated at 180 liters, and it is the best balance of capacity, weight and locking hardware in the aluminium group. At 26 pounds it is light enough to lift alone, and at just over 48 inches long it still fits across most bed widths behind a short-bed wheel well.
The tub is a high-strength aluminium diamond pattern with a polished surface that resists rust and corrosion, and the sealing design is rated waterproof and dustproof rather than merely water resistant. That distinction matters in snow country and on coastal trucks.
Owners repeatedly call out the finish as better than cost-comparable boxes, and the line covers a wide range of sizes in black and silver, so you can size up or down without changing brand. Packing is good, with cardboard and steel corner protectors, and buyers report the company resolving damage claims quickly.
Trailer owners buy the smaller sizes in the same line as tongue boxes and rate them highly, which tells you the shell and latch hold up when the box is strapped to a frame rather than sitting in a bed.
Who this chest suits
This is the box for a working truck that lives outdoors. If you want a lockable aluminium chest, more than 6 cubic feet of volume and a shell you can hose off, this is the pick. It also works well as a secondary box behind a cab or beside a fifth-wheel hitch where a full-width chest would not fit.
Owners of lighter trucks will like the 26 pound weight. That matters on a half-ton where payload is already contested by a bed liner, a hitch and a canopy.
Where it falls short
The latch is the real design quirk. It has to be unlocked before the lid will close, so you carry a key in your pocket in all weather just to shut the box. On the ARKSEN 30 inch underbody in this guide the latch is dual-position, which solves it, but the long chest does not.
The key blanks are also proprietary, so a replacement or spare key is harder to source than a standard pin-tumbler blank. And while the shell is rated waterproof, the lock is a deterrent against opportunistic access, not a strongbox.
4. ARKSEN 30 Inch Underbody – Drop-Down Door Where Space Is Tight
ARKSEN 30″ x 17″ x 18″ Underbody Tool Box, Heavy Duty Storage Chest,Black
Aluminum underbody box
30L x 17W x 18H inches
17.9 pounds
150 liter storage volume
Pros
- Drop-down door gives full access without lifting a lid
- Dual-position latch works with or without the key
- Light at 17.9 pounds so one person can mount it
- Same finish quality as the rest of the ARKSEN range
- No assembly required
Cons
- Key still needed for the secure latch position
- Aluminum sheet is light and will not take hard abuse
- Some units arrive dented despite good packing
The ARKSEN 30 inch underbody box is the one to look at if you have zero bed space to spare. At 30 by 17 by 18 inches and 17.9 pounds, it mounts under the bed, on a trailer frame, in a pickup rack or in a camper, and it gives up nothing in the bed itself.
Access is the reason to prefer this style over a top-lid box. The drop-down door swings fully clear, so you load and unload from the side without crouching over a lid, which is much faster for a tool you grab several times a day. The sealing is rated waterproof and dustproof.
Reviewers cite the same strengths as the longer ARKSEN chest: solid diamond plate, good value for the money and easy drop-down access. The rotating dual-position latch is the improvement here, since it can be operated without the key unless you want it secured.
There is a shared reservation across the ARKSEN reviews, which is that the aluminium sheet sits on the lighter side and will not take heavy abuse. Add weather stripping if you need a tighter seal than the factory fit.
Who this box suits
Pick this one if you routinely carry tall or flat loads, a bike, a generator or a stack of plywood, and you would rather keep all of it. A bed rail mount would be in the way; a full-width chest would remove the usable floor entirely.
It is also a strong second-box option. Many owners run a swing case in the bed and an underbody box at the same time, and at 17.9 pounds this one is easy to lift onto a hitch carrier when you need the bed for something else.
Where it falls short
The aluminium is thin by contractor standards. If you are expecting to climb on it, kick it, or haul gravel in it, go for a heavier gauge box such as the Buyers Products Topsider later in this guide.
Underbody mounting also adds a step. Brackets may need to be sourced separately or fabricated, and you should measure your underbody clearance before you commit to the length. The secure latch position still uses the key.
5. VEVOR 36 Inch Underbody – Trailer and Hitch Workhorse
VEVOR Underbody Truck Box, 36″×14″×16″ Pickup Storage Box, Heavy Duty Aluminum Diamond Plate Tool Box with Lock and Keys, Waterproof Trailer Storage Box with T-Handle Latch for Truck, Van, Trailer
Aluminum alloy underbody box
36L x 14W x 16H inches
24.7 pounds
Rated to 110 pounds of cargo
Pros
- Side-loading drop-down door is quicker to load than any top-lid box
- Thicker aluminium sheet than cheaper boxes in the class
- Weld quality and paint finish described as top notch
- Light for its 36 inch size
- Rubber sealing strip gives a tight seal
Cons
- Diamond plate is thin
- so light duty rather than contractor grade
- Lock is a deterrent and the door can be bent with a pry bar
- Some units arrive with a warped door that leaves a corner gap
- Mounting brackets sold separately
The VEVOR 36 inch underbody box is the value pick in the aluminium underbody class, and it ranks near the top of the Truck Bed Toolboxes category on volume of listings for a reason. At 36 by 14 by 16 inches and 24.7 pounds, it is the longest box here that still mounts under a standard bed without taking bed space.
The aluminium alloy has a thickened panel and a tread pattern designed to resist road rash, and the embedded T-handle latch sits flush with no bulge to catch on a ramp or a rock. It is lockable and ships with two keys, rated to 110 pounds of cargo.
Owners who fit these to trailers and RVs tend to describe the aluminium as thin but sturdy, around 1.5mm, and they like how little the box weighs. Reviewers consistently note the weld quality and paint finish as the best in this price band, and most units arrive intact.
Several owners compare the same box favourably against local and retail pricing for an equivalent product, which is the core of the value case: the specification sheet is closer to a mid-tier box than to a budget box.
Who this box suits
This is the one for a trailer builder, a campervan owner or anyone who needs a box they can move between two vehicles in an afternoon. It mounts on a truck underbody, a trailer frame, a pickup rack or a camper, so the same box works for the work truck and the weekend trailer.
It is also a good fit for chain, strap and consumable storage on a utility trailer, since the side-loading door means you are not lifting a loaded lid in a rainstorm.
Where it falls short
Two things to plan for. The mounting brackets are not included, so budget for brackets or a DIY mount and measure your underbody clearance first, and inspect the door seal on arrival because a warped door leaves a corner that lets water in.
The lock is a deterrent, not security, and the door itself could be bent back with a pry bar. If you are storing high-value tools in an unmonitored location, this is the wrong box.
6. confote 39 Inch – Budget Aluminum Box for Salt Climates
confote 39 Inch Heavy Duty Aluminum Stripes Plated Tool Box Pick Up Truck Bed RV Trailer Toolbox Waterproof Square Storage Organizer with Side Handle, Lock and Keys -39″x 13″x 10″，Black
Striped aluminum box
39L x 13W x 10H inches
20.5 pounds
2.9 cubic feet of capacity
Pros
- Full aluminium construction at the lowest tier price in this group
- Stainless steel latch with lock and keys included
- Weather guard rubber seal in the lid
- Interior lift arms hold the lid open
- Rust and corrosion resistant for coastal use
Cons
- Aluminium is not heavy-wall
- so keep loads light
- Shipping damage and misaligned locks reported on a minority of units
- Prolonged road use can twist the lid slightly
- Customer service responsiveness is inconsistent
The confote 39 inch is the lowest-cost box in the guide that is still a full aluminium box rather than a plastic one, and owners in coastal and salt-prone areas rate it well. At 39 by 13 by 10 inches and 20.5 pounds, it carries 2.9 cubic feet, which is enough for a tow strap, ratchet straps, a jack and a few jugs of fluid.
The striped tread pattern is a stiffening pattern rather than cosmetic, and the stainless steel latch resists the corrosion that eats ordinary plated hardware. A weather guard rubber seal sits in the lid, and interior lift arms hold the door open while you dig through the contents.
Trailer-tongue users are the most enthusiastic owners here. One reported carrying two group 31 batteries and a propane bottle on a travel trailer tongue, mounted with U-bolts, which says a lot about how the shell handles road vibration.
The most useful tip from owners is to add a length of weather stripping if you want a genuinely tight seal. It is a small cost that closes the seam around the lid.
Who this box suits
This suits a weekend user on a budget, or anyone whose truck lives near salt water or gets salted roads eight months a year. Corrosion resistance is the reason to choose it over an equivalent plastic or steel box at the same money, since the aluminium body will outlast both in a wet salt environment.
It is also a natural match for a hitch cargo carrier. At 20.5 pounds with side handles, you can load and unload it without help and take the whole storage compartment with you when you unhitch.
Where it falls short
The aluminium is not heavy-wall. Owners describe it as good but not truly heavy duty, which means light-to-medium loads rather than a full complement of cast iron tools. Treat it as an overflow box rather than your primary tool store.
Quality control varies a little. A minority of owners report units arriving with bent corners and misaligned locks, and a few describe the lid twisting slightly after long highway use. Check the latch alignment before you mount it.
7. FORWODE 39 Inch – Gas Strut Lid That Opens One-Handed
FORWODE 39 Inch Aluminum Truck Tool Box Lockable Truck Bed Tool Box Waterproof Truck Bed Storage Box with Gas Struts & Side Handle Truck Tool Chest for Pickup, Truck Bed, RV, Trailer & Garage (Black)
Aluminum box with gas strut
39L x 13W x 10H inches
Lift-off strut lid
Keyed lock, two keys
Pros
- Integrated gas strut opens the lid one-handed and dampens the close
- Sits below the bed rail so a tonneau cover still fits
- Overlapping lid design sheds water
- Foldable side handles make it easy to lift
- Lockable with two keys and anti-pry protection
Cons
- Riveted fasteners rather than threaded hardware
- limiting real load capacity
- Gas struts are described as overpowered and can launch the lid
- Latch bolt can be misaligned so the lid springs open
- Open gaps around the lid let moisture in
The FORWODE 39 inch is the one to look at if opening a lid while holding a flashlight in your teeth is your main complaint. The integrated gas strut opens the lid one-handed and dampens the close, and at 39 by 13 by 10 inches the whole thing sits below the bed rail so a tonneau cover still fits over it.
The body is powder-coated diamond plate aluminium, chosen for light weight, and the foldable side handles let you lift it into a bed or onto a carrier without hunting for a second pair of hands. The lock takes two keys and has an anti-pry feature around the latch.
Owners treat this as a light-duty box for the average owner rather than a contractor box, and the gas struts plus the easy install are the two things they praise most. One owner lists what fits inside: a gallon of coolant, oil, a tow strap, ratchet straps, a jack and a small compressor.
Customer service comes up often in a positive light, with several owners reporting partial refunds for factory or transit damage. That is worth knowing given how much of the negative feedback is about arrival condition.
Who this box suits
This is a good match for a weekend DIYer, a homeowner and a part-time tradesperson who wants one-handed access and cover compatibility more than they want a fortress. It also works for anyone whose tools get loaded and unloaded in a hurry rather than stored long term.
Because it is listed as water resistant rather than fully waterproof, it pairs well with a truck that has a bed cover or a cap. Under a cover, the open lid gaps stop being a daily concern.
Where it falls short
The fasteners are riveted rather than threaded hardware, and that is the reason several owners cap their real-world load below the headline figure. If you plan to hang heavy tools inside, this is not the box.
Two smaller complaints repeat: the struts are strong enough to launch the lid if you let go, and a misaligned latch bolt can let the lid spring open. Check the latch on installation and add a rubber seal strip if you need weather protection.
8. UWS EC10473 – Heavy-Wall Low Profile Crossover
UWS EC10473 69-Inch Matte Black Heavy-Wall Aluminum Truck Tool Box with Low Profile, RigidCore Lid
0.058 inch welded aluminum crossover
77L x 24W x 17H inches
58 pounds
8.4 cubic feet of storage
Pros
- Thickest welded aluminium tub in the group at 0.058 inch
- Foam-filled RigidCore lid resists binding and adds real strength
- Low profile lid preserves rear window visibility
- Includes a tool tray and screwdriver holders
- Limited lifetime warranty
Cons
- Heaviest box in this roundup at 58 pounds
- Assembly required
- Rated water resistant rather than waterproof
- Limited review history for the brand
The UWS EC10473 is a 69 inch nominal low-profile crossover built from a one-piece tub of welded 0.058-inch aluminium, and it is the most substantial build quality in this group. At 8.4 cubic feet and 58 pounds, it is also the heaviest, which tells you where the material went.
The patented RigidCore lid is filled with solid foam, which resists binding and adds genuine lid strength. That is a feature owners single out repeatedly, and it is one of the reasons the lid feels solid after a few seasons instead of sagging.
The low profile is a visibility feature as much as a clearance feature. Because the lid sits low across the bed, you can still see out of the rear window over it, which is a genuine safety benefit in a work truck parked in traffic.
Pre-drilled mounting slots and included hardware make the install straightforward, and the wide-spread stainless steel paddle handles resist corrosion where plated handles would not. A tool tray and built-in screwdriver holders are included, so the first-day organisation is solved.
Who this crossover suits
This is the crossover to own if you want premium construction and you keep your truck in one bed rail position for years. Electricians, plumbers, HVAC techs and serious DIYers who carry higher-value tools get the keyed storage and the lockable shell that a budget chest cannot offer.
It is also the right call for a truck that lives in a wet climate or on the road, because aluminium will not rust the way a steel box will and the foam-filled lid will not bind in cold weather.
Where it falls short
Weight. At 58 pounds this is a two-person install, and it is a real chunk of your half-ton payload before you add a single tool. Check the door sticker payload figure against your planned load before committing.
It also requires assembly per the included instructions, and it is rated water resistant rather than fully waterproof. Owners accept both tradeoffs in exchange for the limited lifetime warranty, but they are tradeoffs.
9. BLACKHORSE-RACING 48 Inch – Large Drop-Door Box for Campers and RVs
BLACKHORSE-RACING 48 Inch Aluminum Truck Tool Box,Storage Box Black
Striped aluminum drop-door box
49L x 19.5W x 17.5H inches
Keyed stainless locks
Black powder coat
Pros
- Striped reinforcement plus diamond pattern for rigidity
- Stainless steel locks and windproof rubber seals
- Drop-down door opens fully so you can see every item
- Large 48 inch capacity suits camper and RV rear mounting
- Corrosion-resistant construction
Cons
- Lid latches may take several tries before they catch
- Aluminium is thin-walled for contractor use
- Thinner review history than the brands above
The BLACKHORSE-RACING 48 inch box is a large drop-door box with a striped and diamond pattern aluminium body, a black powder-coated finish and stainless steel locks. At 49 by 19.5 by 17.5 inches, it is one of the widest units here and the volume is what you are paying for.
The drop-down door opens fully across the width, so you can see the whole interior rather than fishing a torch into a deep box. Locks are stainless steel, and the windproof rubber seals are what keep road spray and dust out of a camper or RV rear mount.
Owners generally describe it as well built for trailer and RV tongue mounting, with a large interior and locks that work. It is also sold for use on camper van cargo racks, enclosed trailer tongues and RV rears, so the mounting pattern suits bolt-down installs.
The most common note is that the drop-down lid latches can be fiddly to close and the aluminium is thin-walled, so it is closer to a duty trailer box than a contractor box.
Who this box suits
This suits anyone who is not putting it in a truck bed at all, but rather bolting it to a camper, a trailer tongue or an RV rack where width is free and capacity is scarce. It also works as a secondary rear-mount box on a truck with a long bed.
If your main concern is volume and a full-opening door rather than weight, this is a strong option. The interior is wide and shallow enough to sort tools by type.
Where it falls short
Two limits. The latches are the part owners complain about most, with several reporting that the lid needs a couple of attempts before it catches, and the aluminium is thin-walled, so it is not a match for a box you will climb on or hammer.
The review history here is thinner than the brands above, so you are buying on the spec sheet more than on a long body of owner feedback. If the box will live in a truck bed and you want longevity, go up to a heavier gauge model.
10. Aikosin 70 Inch Gull Wing – Half-Box Access in a Crossbed
Aikosin 70 Inch Truck Tool Box Gull Wing Crossover Aluminum Black Pickup Truck Bed Storage, Waterproof Side Truck Box with Lock and Key for RVs, ATVs, Trailer & Truck (70″x20″x13″)
Gull wing crossover box
70L x 20W x 13H inches
Keyed lid locks
Black aluminium, 5 bar tread
Pros
- Dual gull wing lids give half-box access without opening everything
- One-piece heavy-duty aluminium tub
- Double V-Pan lid stiffener resists flex
- Overlapping lid sheds moisture
- Lock and keys included
Cons
- Very thin aluminium that will not take heavy abuse
- Weather stripping is thin and the lid can rattle
- Corners sometimes arrive bent
- Two locks may be keyed differently
The Aikosin 70 inch is the only true gull wing crossover in this roundup, and the split lids are a genuine convenience rather than a styling trick. At 70 by 20 by 13 inches you get cross-bed capacity with two separate lids, so you can open one half and leave the other closed and secure.
The tub is a one-piece heavy-duty aluminium diamond plate with a 5 Bar Tread Pattern, and the lids carry a double V-Pan stiffener for rigidity. The overlapping lid design resists moisture, and a lock and keys are included.
Owners like how well the 70 inch length fits tight bed spaces. One specifically called out a Nissan Frontier King Cab, and several mount these on travel trailer tongues for batteries and gear, where the split access is genuinely useful.
The design gets described as clever and good looking as often as it gets described as useful, which tells you it is a box people are happy to see in the bed.
Who this crossover suits
Pick this if you want a full-width crossbed footprint but you do not want to open the whole lid every time you grab a tape measure. It also fits people who keep two different categories of gear and want them physically separated, one half for consumables and one for hand tools.
It suits midsize and compact trucks particularly well, where a 70 inch box still fits across the bed without stealing the whole usable length.
Where it falls short
The aluminium is very thin, and owners are consistent about that. It is light duty in the way a trailer box is light duty, not in the way a crossover for a contractor is. The weather stripping is also thin enough that the lid can rattle in transit, which wears the seal faster.
Check the latches on arrival, because some units ship with misaligned catches that need bending to line up. Owners also report that the two locks are sometimes keyed differently, so confirm both keys work before you rely on either lid.
11. Buyers Products 1721551 – 0.100 Inch Topsider With No-Drill Mount
Buyers Products 1721551 72 x 13 x 16 Inch Black Aluminum Topsider Box
0.100 inch diamond tread aluminum
72L x 13W x 16H inches
78 pounds
8.67 cubic feet in two bays
Pros
- Thickest aluminium in the guide at 0.100 inch diamond tread
- Die-cast locking T-handles pull doors tight against the seals
- Two recessed drop doors across a 72 inch cabinet
- No-drill J-hooks and side-rail pads included
- Ships fully assembled
Cons
- Heaviest unit here at 78 pounds
- Water resistant rather than waterproof
- 16 inch height needs door clearance to check
- Highest cost in this roundup
The Buyers Products 1721551 is a 72 inch topsider built from 0.100-inch diamond tread aluminium, which is twice the gauge of most boxes in this guide. At 78 pounds and 8.67 cubic feet across two compartments, it is the most professional-grade work truck box we evaluated.
The two recessed drop doors give access across the full 72 inch length, so you are not limited to a single opening. Continuous hidden hinges and aircraft-grade support cables make the doors feel solid over years of daily use rather than sagging after a season.
The die-cast locking T-handles are the piece owners praise most, because they pull the doors firmly against the seals. That gives a much better dust and moisture seal than a rotating paddle latch, and it doubles as the lock. It is a heavier mechanism than anything else in this roundup.
It ships fully assembled, which for a box this size saves an afternoon, and the mounting hardware includes optional J-hooks and side-rail pads for a no-drill setup that bolts to the rail instead of the bed floor.
Who this topsider suits
This is the box for a contractor who lives in the truck. The 0.100-inch gauge takes abuse that thinner aluminium dents, and the bed-rail mount keeps the space underneath open, which is exactly what owners on the Ford Truck Enthusiasts forums say they want.
If you are worried about drilling your bed, the J-hook and rail pad option is the answer. Many enthusiasts keep their bed clean for resale, and a rail-mounted box can be unbolted in minutes.
Where it falls short
Weight is the first constraint. At 78 pounds this is the heaviest unit in the guide, and on a half-ton with a hitch, a bed liner and a canopy already on board, the payload math gets tight fast. The manufacturer asks you to verify rail fit, door clearance and payload capacity before installation.
It is also only water resistant, and the 16 inch height means you need clearance for the doors to swing down. Plan the drop-door arc against your bedside before you commit.

The DECKED Truck Bed Storage System is not a box in the way the other eleven products are boxes. It is a drawer system that fills the bed: full bed-length sliding drawers below, and a heavy-duty flat deck above rated to 2000 pounds, so you keep your hauling capacity while you gain organised storage.
This particular unit fits the Ford F-150 2015-current with a 6 foot 6 inch bed, and it has six compartments with key security. The weatherproof drawer seals have been updated to handle car washes, dust and particulates, and closeout panels reduce what gets airborne.
Owner satisfaction is the highest in the guide, and the reason is consistent: you open a drawer and pull a bin out at waist height rather than crouching over a deep lid. Six drawers also mean you can dedicate a compartment to a task and close the rest.
Being made in the USA from recycled HDPE co-moulded to a galvanized steel sub-frame is a real advantage in winter. HDPE will not rust, and a car wash will not eat it, which is why the weatherproof sealing holds up over repeated seasons.
Who this system suits
This is for the fitter, the mobile technician or the contractor who needs tools at waist height and organised by task. It is also the only option here for a truck that must carry a full load on the deck above while still storing small parts.
It ships with a serious accessory kit: a D-co Case Sixer 16, a D-co Case Halfrack 32, a Drawerganizer bin, two drawer dividers, two shallow and two deep stash bins, and four D-ring tie-downs. That is a real starter organisation, not an empty shell.
Where it closes down the decision
It takes over the bed. You are not adding storage to your truck, you are replacing the bed with a deck and drawers, so anything taller than 12 inches inside the bed is going to be awkward. If you regularly haul tall loads, this is the wrong system.
The keyed lock is an optional accessory and is not included, so plan for that if you park overnight in a high-theft area. And the fit is specific to the truck and bed length, so confirm compatibility before you commit to the platform.
How to Measure Your Bed Before You Buy a Tool Box
Short-bed clearance is the single most repeated complaint in the forums, and it is entirely avoidable with five measurements. Take these before you order anything, and the fit problem disappears.
Usable bed length. Measure from the back of the cab or bed front wall to the inside edge of the tailgate, not the advertised bed length. A 5.5 foot bed gives you about 66 inches, which limits most 69 to 72 inch crossbeds and boxes.
Wheel-well position and height. Measure the distance from the bed front to the leading edge of the wheel well, and the height of the well. A chest that has to clear the wells is limited by the gap between them, not by the full bed width.
Width between the rails. For a bed-rail mount, measure the flat top of the rail, not the widest point of the bed. The Buyers Products Topsider at 72 inches long and 13 inches wide needs a rail long enough to carry it.
Tailgate-down clearance. If you tow with the tailgate down, any full-width chest is out. Owners on the Ford Truck Enthusiasts forums describe the tailgate and trailer tongue jack as the two things that interact badly with a full-width box.
Hitch and cover clearance. Measure the hitch height, the gooseneck clearance if you have one, and the height your tonneau or bed cap needs above the rail. Low-profile and wheel-well boxes are the ones that avoid these conflicts.
Two more practical notes. Bed-rail mounting is popular for a reason: it keeps the space beneath the box open, so sheet goods and plywood still slide in flat. And if you want to avoid drilling the bed entirely, spacers to the factory bedbox cleats are a common reversible approach, so the box can move to another truck later.
If you haul snowmobiles or anything that needs the bed floor open, check that a slide-in drawer system is not blocking your skis or your loading angle. Those are the setups where a swing case or an underbody box simply works better.
Buying Guide: Material, Lock, Mount and Payload
Material decides weight, corrosion and dents. Aluminium is the default for bed boxes because it will not rust and it keeps weight low, but gauge matters more than material. The 0.058-inch UWS tub and the 0.100-inch Buyers Products Topsider are contractor grade, while the thin aluminium in the lower-cost boxes dents when a corner catches. Steel holds heavier loads and takes more punishment but adds weight and will eventually rust at the welds. Polyethylene, like the Buyers Products chest, will not dent or corrode at all, but it is the least secure and can warp in prolonged heat.
Lock type sets your real security level. A plastic latch is convenience only. A keyed latch with a standard or non-standard blank stops casual access. A die-cast locking T-handle that pulls the door against the seal, like the Topsider, is the most secure hardware in this roundup. Whatever you choose, check whether the lock core is all metal, because a steel core meeting aluminium is where corrosion reports tend to start.
Mounting method is about reversibility and bed preservation. Bed-floor mounts with pre-drilled slots are the simplest and the stiffest. Bed-rail mounts preserve the space underneath for sheet goods and can often be unbolted. J-hook and rail pad kits avoid drilling the bed entirely, which matters if you plan to sell the truck. Swing cases bolt to the bedside beside the wheel well, and underbody boxes bolt to brackets under the frame.
Payload and GVWR deserve a real look. A heavy aluminium box can run from 50 to 78 pounds, and that weight is deducted from your payload before you load a single tool. On a half-ton, that is the difference between fitting a snowplow-rated setup and not. Check the payload figure on the door jamb sticker and subtract your box, hitch, canopy and planned load before you order.
Price tiers tell you what you are buying. Below roughly the low end of this range, you are getting thin aluminium and a light lock. In the mid range, you get thicker gauge, better seals and proper hardware. At the top of this range, you are buying gauge, a foam-filled or die-cast latch, real warranty and brand support. That is the honest version of the budget-versus-premium argument: the extra money buys material thickness and hardware quality, not capacity. The same logic applies to the tools themselves, which is why we keep a separate guide to the best cordless tool combo kits for anyone rebuilding a whole kit at once.
Know the failure modes before you buy. Owners report the same five problems repeatedly: locks that stop staying latched after a few seasons, weatherstripping gaps on budget aluminium that need DIY sealing, boxes arriving dented in transit, thin aluminium that takes a hit and stays hit, and a loss of usable bed length that surprises people on short beds. All five are visible in the spec sheets and reviews above, which is why we have flagged them in each block rather than leaving them to be discovered a year later.
One last piece of advice from the forum crowd that applies to every box on this list. Strap it down. Handle-to-tie-down straps or bed-rail clamps stop a heavy box shifting under hard braking, and a box that has slid forward once will rarely sit correctly again. If you are choosing between two boxes of similar quality, choose the one that gives you a positive strap anchor point.
Frequently Asked Questions
Are truck bed tool boxes worth it?
Yes, if you keep tools in the bed and leave them there. A lockable box stops tools sliding, keeps rain and road salt out, and deters opportunistic theft overnight. You also regain bed organisation, since loose gear no longer spreads across the floor. If you only haul bulky items and never store tools, skip it. The UnderCover SwingCase and the Buyers Products poly chest are the most common starting points.
Who makes the best truck tool box?
The premium answer is UWS for a heavy-wall aluminium crossover, and the practical answer is Buyers Products for a poly chest or topsider. Dee Zee, Weather Guard, Westin and CamLocker are the other names that dominate retailer and forum discussions, and owners on the Ford Truck Enthusiasts forums report CamLocker boxes bought decades ago still in daily service. The best brand for you is the one whose gauge and latch match your load.
What is the best crossover truck tool box?
The UWS EC10473 leads our crossover picks because of its welded 0.058-inch aluminium tub and foam-filled RigidCore lid, which resists binding over time. Its low profile also preserves rear window visibility. Buyers looking for a lighter option with split access can consider the Aikosin 70 inch gull wing, though its aluminium is thinner. A crossover mounts on the bed rails, so you keep the space underneath open for sheet goods.
What is the best toolbox for the money?
The Buyers Products 1712240 poly chest is our best value pick. It gives you 6.3 cubic feet in a 28 pound box, takes a standard padlock, and is made in the USA, and owners report it is thick enough to stand on. If you need a lockable aluminium box instead, the ARKSEN 49 inch is the mid-tier answer. Value here means material thickness and hardware, not capacity alone.
What are the common problems with truck bed tool boxes?
Five problems come up repeatedly in owner reports. Lock mechanisms that stop staying latched after a few seasons, especially push-button latches. Thin aluminium that dents permanently on a hard corner. Gaps between the lid and factory weatherstripping on budget boxes. Dented boxes arriving in transit. And a loss of usable bed length on short beds that owners only notice after the box is mounted. All five are avoidable by measuring first and choosing a heavier gauge.
Is UWS or Camlocker better?
Both are respected premium brands and the honest answer depends on the model. UWS is known for thick welded aluminium and the RigidCore foam-filled lid that owners repeatedly single out as a standout feature. CamLocker has the longevity record, with owners on the Ford Truck Enthusiasts forums reporting a crossover bought in 1985 still in daily service. Compare the specific gauge and latch, since both brands build across several tiers.
Are Weatherguard tool boxes worth it?
Weatherguard is a well-regarded premium brand, but owners have reported push-button locks that would not stay latched once locked, and the company reportedly changed lock suppliers. That feedback is model-specific rather than a verdict on the whole brand, so check the latch on arrival and test it before loading anything valuable. If reliable latching is your priority, a die-cast T-handle or a keyed latch is the safer bet.
Do truck bed tool boxes reduce payload capacity?
Yes, and the amount can be surprising. A box in this roundup can weigh from about 16 pounds to 78 pounds, and that mass is deducted from your payload before you add tools, a hitch, a bed liner or a canopy. On a half-ton truck that is a meaningful chunk of the door-jamb payload figure. Check the sticker on your door jamb and subtract the box weight, hitch weight and planned load before ordering.
Can I install a truck bed tool box without drilling?
Usually yes. Bed-rail mounted boxes can use J-hook and rail pad kits that clamp to the rail rather than drilling the bed floor, and the Buyers Products 1721551 ships with that hardware. Another approach is spacing a box off the bed floor and bolting it to the factory bedbox cleats. Both are reversible, which matters if you plan to sell the truck or move the box to another vehicle later.
What is the difference between a crossover and a chest truck tool box?
A crossover spans the full bed width and mounts on top of the bed rails, so the space underneath stays open for plywood and ladders. A bed chest is a deeper box that sits in the bed and takes over the rear of it for more capacity, costing you usable bed length. Crossovers suit owners who haul long materials, while chests suit owners who need volume and can live without the open floor.
What are some good heavy-duty tool boxes for trucks?
For genuinely heavy duty, gauge and hardware matter most. The Buyers Products 1721551 topsider uses 0.100-inch diamond tread aluminium with die-cast locking T-handles, and the UWS EC10473 uses a welded 0.058-inch tub with a foam-filled lid. Both are heavier, at 78 and 58 pounds, so check your payload. Budget aluminium boxes in this roundup are better suited to light-to-medium loads.
