How to Choose the Right Truck Tool Box with Drawers? | Fit Your Bed

Buying the wrong drawer box means wasted bed space, tools that don’t fit, or a box that rattles loose. The fix for choosing the right truck tool box with drawers is matching four things: your truck’s bed, the mounting area, the tools you carry, and how much weight the box can handle. Here’s the practical way to work through those decisions.

What Truck And Bed Fit Do You Need?

Your truck’s bed size and rail style determine which boxes will physically fit. A full-width box designed for a 5.5-foot short bed will not mount cleanly on an 8-foot long bed, and vice versa. You also need to measure the available mounting area—some drawer boxes mount to the bed rail, while others are designed for fender wells or specific utility bodies.

Before buying, always verify the manufacturer’s compatibility notes. DECKED says its Tool Box works with most trucks, and the UWS fender well box is built for a specific mounting location that leaves roughly 4 inches of clearance above the bed rails. If you have a service truck, utility body, or wrecker, measure the open mounting area first so the drawer unit doesn’t block lights, fuel fills, or other hardware. When you’re ready to see tested options side by side, our tested roundup of drawer tool boxes shows how the top picks compare.

Drawer Size, Count, And Organization

Drawer count and depth are the heart of a drawer box. Think about what you carry: small parts and fasteners need shallow, divided drawers, while bulky tools like ratchets and wrenches need deeper ones. Drawer units generally offer single-drawer designs up to multi-drawer systems, with drawer heights typically ranging from 4 inches to 12 inches.

The UWS 18″ Drawer Truck Tool Box (SKU DS-18-BLK) shows how sizing breaks down. It ships with five drawers: two that measure 2″ x 4-3/8″ x 15″ and three that are 3″ x 4-3/8″ x 15″. That’s enough shallow space for a full socket set, but there’s no deep drawer for a heavy impact wrench. If you need to organize small parts, look for drawers with removable dividers—the UWS fender well box includes them, letting you customize compartment widths.

Material, Weight, And Load Rating

Material drives durability and total weight. Aluminum resists corrosion and keeps the box lighter, which matters if you’re already near your payload limit. Steel is stronger but heavier and needs a solid finish to fend off rust. Tread plate aluminum, as seen on the UWS fender well box (0.058 aluminum), adds grip and a professional look but weighs more than a standard aluminum shell.

Check the load rating before you store anything heavy. The DECKED Tool Box handles an 800 lb internal payload—enough for a serious jobsite kit—and its 288 L internal volume gives you room for dual drawers plus stash bins and side access. Compare that to a lighter box that may only handle a few hundred pounds. The box itself adds weight to your truck too; the DECKED weighs 106 lb while the small UWS 18″ unit is a much lighter 27.2 lb.

Locks, Warranty, And Mounting Hardware

Security and weather protection decide how long the box lasts. A lock is essential if you store expensive tools; the DECKED ships with one included. The UWS 18″ carries a limited lifetime warranty that covers one year on finish and parts, which reflects the expectation that powder coat and moving parts wear out before the aluminum shell does.

Mounting hardware is an easy miss. The UWS fender well box does not include mounting hardware, so factor the cost of bolts and brackets into your budget. Before finalizing a purchase, run this checklist: confirm the box fits your specific bed, verify the drawer depths will hold your largest tool, check the load rating against your heaviest kit, and make sure you have the mounting hardware on hand.
