How the points were given
Each box is scored on performance, build, value, safety, and warranty, with the weights published on our How We Pick page. For boxes, safety means locks, latches, and seals that keep tools secured and dry. Only the DEWALT case states a concrete warranty term, so the other four score zero on warranty.

How to choose the best large truck tool box
Size and mounting decide what fits
The VEVOR bed box measures 48 x 15 x 15 inches and sits in a pickup bed, while the FGJQEFG box measures 48 x 18 x 18 Inch for underbed trailer use. The Buyers box and the VEVOR underbody box both measure around 36 inches long, with the Buyers box at 36 x 18 x 18-inch and the underbody box at 36 x 17 x 18 inches. Measure the bed or underbody space before ordering, since the underbody box listing warns buyers to measure the vehicle underbody space first.
Material and weather seal
Aluminum boxes resist rust and corrosion and stay light: the VEVOR bed box weighs 25.6 pounds and the underbody box weighs 28.4 Pounds. Steel boxes weigh more and suit heavy work: the Buyers box uses 14-gauge steel and weighs 76.0 pounds, and the FGJQEFG box is steel at 69.1 pounds. Seals matter in rain and on dusty roads. The VEVOR bed box has an overhanging door with a tight seal, the underbody box has a rubber sealing strip, and the Buyers box uses a continuous hidden hinge with a replaceable gasket system.
Locks and access
Every box here locks. The VEVOR bed box has a stainless steel locking mechanism with 2 exclusive keys, and the underbody box has a lockable T-handle with two exclusive keys. The Buyers box uses a stainless steel locking T-handle compression latch that pulls the recessed drop door against the gasket. The FGJQEFG box has a lock and key with sealing. For access, the VEVOR bed box opens with a gas strut to 110 degrees, and the Buyers box door opens downward with aircraft-grade support cables.
What about the portable case
The DEWALT case is not a truck bed box. It is a 13 In. stackable case with side latches and a bi-material handle, and it holds up to 66 lbs. It suits small tools carried to the truck, while the bed and underbody boxes suit tools stored on the truck itself.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Measure the bed, underbody, or flat surface before ordering, and check clearance for a drop-down door.
- Check mounting: the Buyers box notes mounting brackets are sold separately, and the VEVOR underbody box notes brackets can be purchased for installation.
- Count the keys at delivery: the VEVOR boxes each come with 2 keys, and the other boxes come with a lock and key or a locking latch.
- Check the seal and latch before the first loaded trip, since seals and gaskets keep tools dry on the road.
- Keep the portable case for small tools: it stacks with other units and holds up to 66 lbs.
