A cargo box on a work truck is not a lifestyle accessory. It is the difference between a tailgate covered in loose impact drivers and a locked, gasketed compartment you can find a 3/8 socket in at 6:40 a.m. in the rain.
This roundup reads the published specifications for ten boxes that a contractor, service tech or van-based trade could realistically bolt to a vehicle: aluminum topsider boxes, slide-out bed trays, an underbody box, a hitch-mounted chest, and two sealed rugged cases. This website does not do hands-on testing. What follows is a close reading of manufacturer and listing specifications, plus blunt opinions about which spec suits which job.
One thing up front, because it matters more than any feature bullet: a published box dimension is not a fit confirmation, and a box's own weight rating is not your vehicle's payload. Confirm mounting points, clearances and every applicable vehicle, rack and hitch limit before you load anything.

What to Look For in a Job-Site Cargo Box
Buy for the mounting location first, the seal second, the lock third. Everything else is preference.
- Mounting location. A topsider sits across the bed front and eats bed length. An underbody box hangs off the frame rail and eats nothing. A slide-out tray uses the bed floor but needs a cover. A hitch carrier uses none of the above and adds rear overhang. These are not interchangeable.
- Material and gauge. Aluminum thickness is published as a number, and that number is the only honest way to compare two look-alike diamond-plate boxes. Polyethylene resists dents but is a different engineering tradeoff entirely.
- Sealing. Look for a stated gasket or sealing strip. "Weather-resistant" without a named seal component is marketing.
- Locking. A stated lock, latch or pad-lockable hasp is a real feature. A missing lock field in a listing is unknown, not proof the box is insecure — but if security is the reason you are buying, buy one where the lock is explicitly specified.
- Stated fit list. Some listings name the exact trucks. Those are far easier to shop than a bare width.
- Load limits. Only buy on a weight number when the manufacturer publishes one, and remember that a volume figure is not a weight allowance.
The Picks
Buyers Products 1725641 72 Inch Black Aluminum Contractor Tool Box — Best for a full-width topsider with sorted drawers on a daily job-site pickup
This is the classic contractor topsider layout, and the spec sheet explains why trades keep buying the shape. Buyers publishes a large flip-up upper compartment for bulky tools and supplies, plus two lower drawers with adjustable dividers for smaller parts and frequently used equipment. That two-tier arrangement is the whole argument: consumables and fasteners live in drawers you can open standing at the side of the bed, while the long, awkward stuff goes up top.
The body is listed as .056-inch black diamond tread aluminum, described by the manufacturer as corrosion-resistant and suited to pickups, utility bodies and demanding job-site applications. Security comes from stainless steel compression latches on both the upper compartment and the drawers, which the listing says also keep doors and drawers firmly closed during travel. Sealing is handled by replaceable gasket seals against moisture, dust and road debris — the word replaceable is the part worth noticing, because a gasket is the first thing to die on a box that gets slammed shut forty times a day.
Buyers also specifies aircraft-grade support cables that control the flip-up door and help protect the hinge through repeated opening and closing. Dimensions are 72 x 21 x 13.5 inches with mounting hardware included, and the listing itself tells you to confirm truck fit, lid and drawer clearance, mounting support, payload capacity and access before installation and loading. Take that instruction literally — 72 inches across is a full-size bed proposition, and rear-window and lid-swing clearance are yours to verify.
Pros
- Two-tier layout with a flip-up upper compartment plus two divider-equipped lower drawers
- Stainless steel compression latches specified on both the upper compartment and the drawers
- Replaceable gasket seals, so the weather barrier is a serviceable part
- Support cables specified to control the flip-up door and protect the hinge
- Mounting hardware included
- At 72 x 21 x 13.5 inches it consumes real bed length and needs verified clearance before you commit
- The supplied listing information does not state a load capacity or a warranty length
Verdict: Buy this if you run a full-size pickup, want parts drawers rather than one cavernous bin, and value a gasket you can replace instead of a box you have to.
VEVOR Contractor Truck Tool Box, 72 x 21 x 13 in — Best for a thicker-gauge aluminum topsider with quick J-hook mounting
Here's the interesting comparison in this whole roundup. VEVOR lists this topsider at 0.07-inch thick aluminum; Buyers lists the 1725641 at .056-inch aluminum. Same broad footprint, different published gauge. Thicker sheet on paper suggests a stiffer, more dent-tolerant shell, though gauge alone does not establish overall strength, and neither listing publishes a comparable impact or load figure to settle it.
The layout mirrors the contractor standard: a flip-up door over a long main cavity that VEVOR says is built for long tools like drills, cables and crowbars, with two lower drawers for layered organization of small items. Construction details called out include solid welding to preserve shape and fixed rods to keep it in place on rough roads. The box measures 72 x 21 x 13 inches.
Security is a two-position latch that VEVOR describes as keeping tools and valuables secure from unauthorized access with a smooth-turning lock. Weather protection comes from stainless steel hinges and a sealing strip against rain, snow and dust. Mounting uses included J-hooks, which the manufacturer frames as fast, secure and easy to detach — that matters if you swap the box between a pickup, a flatbed and a utility truck, all three of which VEVOR lists as intended applications. J-hooks are still a clamp-style mount, so verify bed rail support and that nothing fouls the rear glass.
Pros
- 0.07-inch aluminum, the thicker of the two published topsider gauges here
- Long main cavity specified for drills, cables and crowbars, plus two drawers for small parts
- Two-position locking latch with a smooth-turning lock
- Stainless steel hinges and a sealing strip for rain, snow and dust
- J-hook mounting for quick fitting and detachment across pickup, flatbed or utility truck
- The supplied listing information does not state a load capacity or warranty term
- No specific vehicle fit list is published, so bed-width and clearance checks are entirely on you
Verdict: The pick for a contractor who wants the thickest published aluminum gauge in this group and the ability to pull the box off one truck and hook it onto another.
VEVOR Underbody Truck Box, 30" x 17" x 18" Pickup Storage Box — Best for service vehicles, trailers and vans with no bed space to surrender
Look, if you drive a van or a flatbed, the topsider conversation is over before it starts. An underbody box hangs where nothing else lives. VEVOR publishes this one at 30 x 17 x 18 inches (760 x 432 x 457 mm) in aluminum diamond plate, and explicitly tells buyers to measure the vehicle's underbody space before purchasing.
The hardware choices read like they were made for a truck that lives on gravel. The T-shaped handle is embedded rather than protruding, which VEVOR says makes it resistant to scratches and hits during driving — a sensible design for a box mounted at frame height where a curb or a snow bank will find anything that sticks out. The box is lockable and ships with two keys. A rubber sealing strip creates a tight seal when closed to keep water out, and the aluminum alloy body is described as rust- and corrosion-resistant compared with iron, with a thickened, tread-patterned panel meant to resist damage and scratching over long-term road driving.
Mounting is the honest caveat. VEVOR states you can purchase brackets to install it or do a DIY assembly yourself — meaning the box is not a bolt-on kit for your specific frame out of the carton. The manufacturer also warns that if you assemble the box on the vehicle, you should turn off the power to prevent a short circuit. Underbody mounting near frame rails, wiring, fuel and exhaust is exactly the situation where you follow the manufacturer's instructions or hand it to an upfitter rather than improvising. VEVOR also notes the box can be installed in other locations, such as the back of a camper or a pickup rack.
Pros
- Frees bed and cargo-floor space entirely by mounting underneath
- Lockable with two keys, and the T-handle is recessed to resist road strikes
- Rubber sealing strip specified to keep water out
- Aluminum alloy with a thickened tread panel for corrosion and scratch resistance
- Flexible placement, including camper backs and pickup racks
- Brackets are a separate purchase or a DIY job; this is not a vehicle-specific bolt-on
- The supplied listing information does not state a weight capacity
- Underbody clearance must be measured before ordering, per the manufacturer
Verdict: The right answer for service vans, trailers and flatbeds where storage has to go somewhere other than the load floor — provided you sort out proper brackets and a safe install.
Full Size Truck Bed Cargo Box - Slides Out Onto Tailgate for Easy Access to Load and Unload — Best for full-size trucks already running a tonneau or cap
The Last Boks concept is a giant drawer. It pulls out through the bed opening onto your tailgate, and the manufacturer is careful to say it is not a stationary bed liner — it slides in and out at your convenience. For a tradesperson who currently belly-crawls into a covered bed to reach a tool bag at the bulkhead, that is the entire value proposition.
The full-size version measures 56 inches wide by 24 inches deep by 11 inches high and weighs 20 lbs. It is made in the USA from high molecular weight polyethylene with a skid-resistant cap, and the manufacturer describes it as water resistant and waterproof against spills and messy cargo, hose-off cleanable. The published fit list is specific and useful: Ford F150, F250 and F350, Chevy Silverado 1500/2500/3500, GMC Sierra 1500/2500/3500, Dodge Ram 1500/2500/3500, Toyota Tundra and Nissan Titan.
Now the hard requirement, and it disqualifies plenty of work trucks: the manufacturer states this cargo box should never be used in an open truck bed, and that a tonneau cover or truck cap is required to operate safely. If your truck runs an open bed, this is not your box. The listing also notes that if you have a GM bed liner with storage behind the wheel wells, you should use the mid-size version instead. No load rating is stated in the supplied listing information, so treat it as an organizer and access solution rather than a specified-capacity job box.
Pros
- Slides out onto the tailgate so bulkhead cargo is reachable without climbing in
- 20 lbs, so it is manageable to remove when the bed is needed for material
- High molecular weight polyethylene with a skid-resistant cap, hose-off cleanable
- Named fit list covering F-Series, Silverado, Sierra, Ram, Tundra and Titan
- Requires a tonneau cover or truck cap; the manufacturer says it must never be used in an open bed
- The supplied listing information does not state a weight capacity or a lock
- GM bed liners with behind-the-wheel-well storage push you to the mid-size unit
Verdict: Best for the full-size truck owner who already has a cover and is tired of reaching for gear at the front of the bed.
Last Boks Mid Size Truck Bed, Cargo Box Organizer — Best for covered mid-size pickups running Tacoma, Ranger or Colorado duty
Same drawer concept, scaled for the trucks a lot of one-van trades and inspectors actually drive. The mid-size unit measures 52 inches wide by 23 inches deep by 11 inches high and weighs 17 lbs — three pounds lighter and four inches narrower than the full-size version, which is exactly the kind of difference that decides whether the box clears your wheel wells.
Materials match: made in the USA from high molecular weight polyethylene with a skid-resistant cap, water resistant and waterproof, and hose-off cleanable if something spills inside. The published fit list is Ford Ranger, Chevy Colorado, GMC Canyon, Toyota Tacoma and Nissan Frontier. The manufacturer also notes that if you have a GM bed liner with storage behind the wheel wells, the mid-size is the one to use — which is worth knowing if you were otherwise sizing up.
The same safety condition applies. The manufacturer states a tonneau cover or truck cap is required to operate safely and that it should never be used in an open truck bed. No weight rating appears in the supplied listing information. Treat the 11-inch height as a real constraint too: this is a box for tool bags, cases, fasteners and cords, not for a stacked load of tile.
Pros
- 17 lbs, the lightest box in this roundup by published weight
- Pulls out onto the tailgate for full-length access under a cover
- Named fit list: Ranger, Colorado, Canyon, Tacoma, Frontier
- Waterproof HMW polyethylene that hoses clean
- Cover or cap required; the manufacturer prohibits open-bed use
- 11-inch interior height limits what will stand up inside
- The supplied listing information does not state a load capacity or a locking mechanism
Verdict: The mid-size truck version of the same good idea — get it if you run a covered Tacoma, Ranger, Colorado, Canyon or Frontier.
Rough Country 52.25" Slide-Out Truck Bed Cargo Box — Best for mid-size beds that need depth and a stated warranty
Rough Country's mid-size slide-out measures 52.25" x 23" x 16.5" H and is built from UV-protected high-density polyethylene that the manufacturer describes as weather resistant and designed to resist fading. Against the Last Boks mid-size at 52 x 23 x 11 inches, the Rough Country is 5.5 inches taller with essentially the same footprint — meaningfully more vertical room for tool cases and buckets, at the cost of stacking height under your cover.
Rough Country addresses that directly, saying the 16.5-inch height fits under virtually any bed cover and that the 23-inch depth suits larger cargo. That is the manufacturer's claim, not a measurement taken here, and "virtually any" is not a fit guarantee — measure your specific cover's interior clearance. Retention is handled by adjustable tie-down straps that attach to built-in hook points to hold the tray in place during loading and unloading from the tailgate.
The standout spec for a contractor is administrative rather than physical: Rough Country backs it with a 3-year warranty. Very few boxes in this group publish a warranty term at all, and on a box that gets slammed shut daily for years, a stated multi-year term is a real reason to choose one polyethylene tray over another.
Pros
- 16.5-inch height gives more vertical room than the 11-inch mid-size slide-out alternatives
- UV-protected high-density polyethylene specified to resist fading
- Adjustable tie-down straps and built-in hook points to hold the tray in place
- 3-year warranty published by the manufacturer
- The supplied listing information does not state a weight capacity or a lock
- Taller profile means cover clearance needs checking despite the "fits under virtually any bed cover" claim
- Fit is described as "popular mid-size pickup truck models" without a named vehicle list
Verdict: The mid-size slide-out to buy if you want maximum interior height and a manufacturer warranty in writing.
Rough Country 48" Slide-Out Truck Bed Cargo Box — Best for short full-size beds and low-clearance covers
The 48-inch version is the low-profile sibling, measuring 48"L x 20.5"D x 12.37"H, and Rough Country states it fits popular full-size pickup truck models with short beds. At only 12 inches tall by the manufacturer's description, it is built for the truck where your tonneau or roll-up cover sits close to the rails and the taller 16.5-inch tray simply will not go in.
Construction matches the mid-size unit: durable high-density polyethylene, UV protected to prevent fading, and described as weather resistant against tough conditions. Same securement system too — adjustable tie-down straps clipping into built-in hook points so the tray stays put while you slide it out onto the tailgate. And the same 3-year Rough Country warranty applies.
The tradeoff is volume. Compared with the 52.25-inch mid-size box, you give up 4.25 inches of length, 2.5 inches of depth and roughly 4 inches of height. For a plumber or electrician carrying cases, cords and hand tools, that is fine. For anyone hauling tall buckets or a stacked load, it is a real constraint you should check against your actual kit before ordering.
Pros
- 12.37-inch height suits low-clearance bed covers
- UV-protected high-density polyethylene, weather resistant per the manufacturer
- Tie-down straps and built-in hook points for securement during tailgate access
- 3-year Rough Country warranty
- Smallest of the two Rough Country trays in every published dimension
- The supplied listing information does not state a weight capacity or a lock
- Fit described only as "popular full-size pickup truck models" with short beds
Verdict: Get this one if your cover sits low or your bed is short, and you want the Rough Country warranty in a smaller footprint.
Buyers Products 1707020 Poly Hitch Mounted Cargo Carrier — Best for adding lockable volume behind a van or an already-loaded truck
Here's the thing about work vans: the cargo area fills up, and you cannot mount a topsider on a van roofline the way you can on a pickup bed. A hitch-mounted chest sidesteps the whole problem. Buyers publishes this one at 23x51x26 inches, sliding into a 2-inch receiver hitch, and frames it as adding storage without sacrificing passenger space.
The build is a polyethylene chest on a black powder-coated steel frame. Buyers describes the polyethylene as dent-resistant, high density, with a double-walled lid and waterproof protection, and the steel frame as corrosion-resistant and pre-drilled for easy assembly. A 5/8-inch hitch pin is included, and the carrier is made in the USA. Security comes from two pad-lockable hasps on that double-walled lid — padlocks sold separately, which is a small annoyance but at least the hasps are engineered in rather than added later.
Capacity is the number that matters and Buyers actually publishes it: the bin holds up to 200 lbs and offers 17 cubic feet of functional space. Treat those as two independent limits, not one. Seventeen cubic feet of volume does not entitle you to exceed 200 lbs, and the 200 lb bin rating tells you nothing about your hitch's tongue weight rating or your vehicle's payload. A loaded carrier hanging well behind the rear axle also changes how the vehicle handles. Check your receiver class, your tongue weight limit and the carrier's own capacity, and satisfy the lowest of the three.
Pros
- 200 lb stated capacity and 17 cubic feet of functional space, both published by Buyers
- Two pad-lockable hasps on a double-walled lid
- Dent-resistant high-density polyethylene on a corrosion-resistant powder-coated steel frame
- Fits a 2-inch receiver and includes the 5/8-inch hitch pin
- Frees interior and bed space entirely
- Padlocks are sold separately
- Requires a 2-inch receiver, and your hitch and vehicle limits may be lower than the bin's 200 lb rating
- Assembly required, though the steel frame is pre-drilled
Verdict: The most sensible added-volume option for a full work van or a truck whose bed is already spoken for, as long as your receiver and tongue weight limits clear it.
ROAM Rugged Cargo Box — Best for a sealed, mount-flexible case that moves between roof rack and bed
ROAM's rugged case is the one product here that does not assume a fixed home. The manufacturer says it can be mounted using Rugged Mounts, Rigid Mounts or Cinch Straps depending on size, on roof racks, truck beds or other setups, and that tie-down channels keep it secure in a bed or on a rack. For a trade that works out of a van one day and a shared truck the next, that portability is the whole point.
The protection spec is the strongest language in this group. ROAM describes a military-grade weatherproof seal against rain, dust and extreme conditions, an impact-resistant shell with an interlocking design, and lockable latches to protect contents from tampering and the elements. Lid-lift gas struts hold the lid open hands-free, and ROAM says the struts also help prevent warping over time — useful when you are pulling parts out one-handed off a ladder.
Customization is a genuinely contractor-friendly touch: threaded inserts let you add lid organizers or MOLLE panels, so the case can be configured for a specific trade kit rather than used as one open bin. The honest gap is numbers. The supplied listing information for this case does not state dimensions, capacity or weight, and the mounting hardware is described as size-dependent. Nail down which size and which mount system you need before ordering, and confirm the roof rack's own load rating separately if it is going overhead.
Pros
- Mount options across roof racks, truck beds and other setups, with tie-down channels
- Military-grade weatherproof seal claimed by the manufacturer against rain, dust and extreme conditions
- Lockable latches plus an impact-resistant, interlocking shell
- Gas strut lid for hands-free access
- Threaded inserts for lid organizers or MOLLE panels
- The supplied listing information does not state dimensions, capacity or weight for this case
- Mounts vary by size and are described as separate components
- "Military-grade seal" is the manufacturer's own description, not an independently verified certification
Verdict: For the tradesperson who needs one sealed, lockable case that can ride on a rack, in a bed, or in the back of a van without a permanent install.
SRX-110 Overlanding Cargo Case – 110L Waterproof Storage Box — Best for a fully specified, stackable sealed case
This one publishes the numbers the ROAM listing leaves out, which makes it far easier to plan around. External dimensions are 47.2" x 18.4" x 13.2", internal dimensions are 42.5" x 12.7" x 8.5", and the case weighs 37.5 lbs. Capacity is listed at 110L.
Pay attention to the gap between those two dimension sets. External length is 47.2 inches; usable internal length is 42.5 inches. That 4.7-inch difference is wall and gasket, and it is exactly what catches people who buy on the outside number and then find a 44-inch level will not lie flat. Internal height of 8.5 inches is the tighter constraint for most tool cases.
The feature set reads like a working box rather than a camping novelty: waterproof protection via a rubber gasket, lockable latches, a gas strut lid for effortless opening, an internal tray and divider for organization, a built-in drain for easy cleaning, and a stackable design. The drain matters more than it sounds — a sealed box that fills with grout slurry or sawdust is a lot easier to deal with when you can hose it and let it out the bottom. There are also dual bottle openers and optional reflective stickers, which are exactly as job-site-relevant as they sound. The 37.5 lb empty weight is worth noting before you plan to lift a loaded one onto a roof rack solo; the supplied listing information does not state a load capacity.
Pros
- Fully published dimensions inside and out, plus 110L capacity and a 37.5 lb weight
- Waterproof rubber gasket with lockable latches
- Gas strut lid, internal tray and divider, and a built-in drain for cleanout
- Stackable design for storing several at the shop
- Internal height is 8.5 inches, so tall items will not fit
- 37.5 lbs empty before any gear goes in
- The supplied listing information does not state a load capacity or a warranty
Verdict: The sealed case to buy when you need to know exactly what fits before you order, and want a drain and a stackable shape for shop storage.

How We Research
This website does not perform hands-on testing, and nobody here has handled, installed or loaded any of these boxes. Our method is document-driven: we pull each product's Amazon Creators API verified product record, read every published listing feature bullet line by line, and compare the stated dimensions, materials, gauges, seals, latches and capacities across the group.
Where two products publish the same attribute — aluminum thickness, tray height, box weight — we compare those figures directly and say what the difference likely means for a working vehicle. Where a listing is silent on a spec, we say it is not stated rather than guessing or treating the blank as a zero. Claims about material quality, waterproofing or security are attributed to the manufacturer that made them, because a seller's claim is not independent verification. For general product safety background, the CPSC and USA.gov consumer protection pages are the right starting points.
Recommendations by Use Case
Daily job-site pickup, sorted parts: The Buyers Products 1725641 72 Inch Black Aluminum Contractor Tool Box. Two lower drawers with adjustable dividers plus a flip-up upper compartment, stainless steel compression latches on both, and replaceable gasket seals — that combination suits a crew that needs fasteners in a drawer and conduit up top.
Thickest published aluminum and a swappable mount: The VEVOR Contractor Truck Tool Box at 0.07-inch aluminum with J-hook mounting, which VEVOR describes as working on pickup, flatbed or utility truck.
Van, flatbed or trailer with no floor space to give: The VEVOR Underbody Truck Box at 30 x 17 x 18 inches, lockable with two keys and a recessed T-handle. Budget for brackets and a proper install.
Covered full-size truck: The Full Size Truck Bed Cargo Box at 56 x 24 x 11 inches and 20 lbs, with a named fit list for F-Series, Silverado, Sierra, Ram, Tundra and Titan — but only if you already run a tonneau or cap, which the manufacturer requires.
Covered mid-size truck: The Last Boks Mid Size Truck Bed, Cargo Box Organizer at 52 x 23 x 11 inches and 17 lbs, listed for Ranger, Colorado, Canyon, Tacoma and Frontier.
Most interior height in a mid-size tray, with a warranty: The Rough Country 52.25" Slide-Out Truck Bed Cargo Box at 16.5 inches tall with a 3-year warranty. For low covers and short beds, the Rough Country 48" Slide-Out Truck Bed Cargo Box at 12.37 inches tall carries the same 3-year term.
Extra lockable volume without touching the bed: The Buyers Products 1707020 Poly Hitch Mounted Cargo Carrier — 17 cubic feet, a 200 lb bin rating, two pad-lockable hasps, 2-inch receiver.
One sealed case across multiple vehicles: The ROAM Rugged Cargo Box for mounting flexibility and threaded inserts, or the SRX-110 Overlanding Cargo Case when you need published internal dimensions of 42.5" x 12.7" x 8.5" to confirm what actually fits.
Final Verdict
If you want one answer for a contractor's daily-driver pickup, it is the Buyers Products 1725641 72 Inch Black Aluminum Contractor Tool Box. The reason is specific and on the spec sheet: a two-tier layout with a flip-up upper compartment and two divider-equipped lower drawers, stainless steel compression latches securing both levels, and gasket seals that are replaceable rather than disposable. That is a box designed to be serviced and used for years, not just filled.
If your aluminum-gauge instinct is stronger than your brand instinct, the VEVOR Contractor Truck Tool Box publishes 0.07-inch aluminum against the Buyers box's .056-inch, and its J-hooks let you move it between trucks. If you drive a van or a flatbed, neither topsider applies and the VEVOR Underbody Truck Box or the Buyers Products 1707020 Poly Hitch Mounted Cargo Carrier is the honest recommendation.
Whatever you pick, the manufacturer's own installation warnings are not boilerplate. Buyers explicitly tells you to confirm truck fit, lid and drawer clearance, mounting support, payload capacity and access before loading. Last Boks explicitly prohibits open-bed use. VEVOR explicitly tells you to measure underbody space and kill the power before assembling on the vehicle. Follow those, and confirm every applicable vehicle, hitch and rack limit separately.
Frequently Asked Questions
Which topsider box has thicker aluminum? By published figures, the VEVOR is thicker. VEVOR lists 0.07-inch aluminum for its 72 x 21 x 13 in contractor tool box, while Buyers lists .056-inch black diamond tread aluminum for the 1725641. Thicker sheet suggests better dent tolerance, but neither listing publishes a comparable impact or load rating, so treat that as an inference rather than a proven difference.
How much weight can a hitch-mounted cargo carrier hold? Buyers publishes a 200 lb capacity and 17 cubic feet of functional space for the 1707020 carrier, which fits a 2-inch receiver. That is the bin's own rating only. Your hitch class, tongue weight limit and vehicle payload are separate limits with their own definitions, and you must satisfy the lowest applicable one including the weight of the carrier itself.
Can I mount an underbody tool box myself? VEVOR states you can purchase brackets to install its 30 x 17 x 18 in underbody box or do a DIY assembly yourself, and warns that if you assemble it on the vehicle you should turn off the power to prevent a short circuit. It also tells buyers to measure underbody space before purchasing. Given the proximity to frame rails, wiring, fuel and exhaust on most service vehicles, following the manufacturer's instructions or using a qualified upfitter is the sensible route.
Which of these boxes actually lock? Several publish a locking mechanism. Buyers specifies stainless steel compression latches on the 1725641's upper compartment and drawers; VEVOR specifies a two-position locking latch on its topsider and a lockable T-handle with two keys on the underbody box; Buyers specifies two pad-lockable hasps on the 1707020, with padlocks sold separately; ROAM and the SRX-110 both specify lockable latches. Where a listing here does not state a lock, that is an unknown in the supplied information, not proof the box has none.
What is the lightest cargo box in this roundup? By published weight, the Last Boks Mid Size Truck Bed, Cargo Box Organizer at 17 lbs, followed by the full-size Last Boks at 20 lbs and the SRX-110 Overlanding Cargo Case at 37.5 lbs. Weights are not published in the supplied listing information for the other boxes, so this comparison covers only those three.
Does any of these come with a warranty? Rough Country publishes a 3-year warranty on both its 52.25-inch and 48-inch slide-out cargo boxes. The supplied listing information for the other products in this roundup does not state a warranty term, which means it is unknown here rather than absent from the manufacturer's own documentation.
Sources & Methodology
No box in this article was physically installed, loaded or laboratory-tested by this website, and we run no test facility. What we did instead was work through each product's Amazon Creators API verified product record and its published listing feature bullets, retrieved 2026-09-11, pulling out the figures manufacturers actually commit to in writing — aluminum thickness, tray and case dimensions, empty weights, seal and latch hardware, stated capacities and warranty terms — and lining them up against each other so the tradeoffs are visible.
That approach is genuinely useful in this category, because cargo boxes are bought on fit and sealing far more than on feel: a 16.5-inch tray either clears your tonneau or it does not, an 8.5-inch internal height either swallows your case or it does not, and a 200 lb bin rating is a number you can check against your hitch. What spec reading cannot tell you is long-term latch durability, gasket life after a few hundred slams, or how a specific box behaves on your particular frame — for those, the manufacturer's fit documentation and your own measurements are the final word.
