Truck bed tool boxes range from $100 for basic plastic chest boxes to $400-$900 for full-size aluminum or steel crossover boxes. Aluminum resists rust and weighs less (helpful for payload-sensitive trucks), while steel (often powder-coated) is tougher against impact but heavier and needs more rust upkeep. Measure your bed width and check ground clearance before buying — an oversized box can block bed rail accessories or tonneau covers.

| Side-mount box | $150-$400 |

| Underbody/saddle box | $150-$450 |
Crossover, side-mount, or chest — which style fits your bed?
Crossover boxes mount across the bed rails behind the cab and free up the rest of the bed floor for cargo — the most popular choice for contractors who need both tool storage and hauling space. Side-mount boxes sit along one bed rail, leaving more floor space but less storage volume. Portable chest boxes sit directly on the bed floor and can be removed entirely when not needed, at the cost of eating into usable bed length.
Material comparison
- Aluminum (diamond-plate or smooth): lightweight, rust-resistant, scratches show less on diamond-plate finish
- Steel: higher impact resistance and often lower cost, but needs a rust-resistant coating and regular inspection in salt/road-de-icer climates
- Poly/plastic: cheapest, fully rust-proof, but lower weight capacity and easier to pry open — best for lower-value tools
Sizing and clearance
Measure the exact bed width at the rail-to-rail point before ordering — full-size vs. mid-size trucks (and different model years) use different bed widths, and a crossover box that doesn't match can leave gaps or fail to seat properly. Also confirm clearance with any existing tonneau cover, bed liner, or cap; low-profile boxes exist specifically for trucks running a roll-up tonneau cover.
Security features to look for
- Weatherproof gasket seal to keep tools dry
- Push-button or T-handle locks; upgrade to a keyed cylinder if the stock lock feels flimsy
- Gas-strut lid supports so the lid doesn't slam or fall on hands
- Mounting clamps rather than drilled bolts, if you want to avoid permanent bed modification
A large crossover box can block rear window visibility on some truck cab configurations — check sightlines before committing, especially on regular-cab short-bed trucks.
Who it suits
Full-size crossover boxes suit tradespeople who carry a heavy, fixed tool set daily and want bed floor space preserved. Someone who only occasionally needs lockable storage — say, for weekend projects — is often better served by a portable chest box that can be removed when hauling larger cargo.
