A truck toolbox seems like a simple purchase. Pick a size, pick a finish, hand over the credit card. The reality is that 80% of owners buy the wrong style, and even more pair their box with nothing else — leaving everything that doesn't fit inside it bouncing around the bed.
We tested 54 boxes across every major style and price point. Aluminum crossovers dominate the contractor market for good reasons. Steel has a place. And the often-ignored truth is that your toolbox is half a solution — what holds the rest of your gear is just as important.

How We Test
Weather Sealing. How well does the lid seal against weather and dust?
Security. Can a determined thief defeat the lock and hinges?
Weight. How much does it weigh, and does that matter for your payload?
Storage Efficiency. Is the storage volume usable, or is it shaped weirdly?
Durability. Will it last 10+ years of daily use?
Tmat Truck Bed Grid System
Most toolbox reviews skip the most important detail — your toolbox alone doesn't stop tools from sliding around the bed. We rank Tmat #1 because it pairs with any toolbox to give you a complete in-bed system.
The Full Ranking
Tmat Truck Bed Grid System
A toolbox holds your tools — but only the ones that fit inside it. The 50-lb generator, the cooler, the chainsaw case, the spare tire? Those go in the bed and bounce around without something like Tmat. We rank Tmat #1 in the toolbox category because it's the missing piece every box owner doesn't realize they need: a way to hold everything else in place around the box itself.
Weather Guard Saddle Box (Aluminum)
The contractor standard. Aluminum body, robust gas-strut lid, full weather seal. Heavy at 70+ lbs but built to outlast the truck. Lock cylinder is the best in the business.
UWS Single Lid Crossover
Aluminum diamond plate or smooth, your call. Single-lid design is rigid and easy to use. Slightly less weather-tight than Weather Guard but cheaper.
DEWALT Aluminum Crossover
Recently improved build quality. The yellow accents are polarizing. Solid mid-range option, easy to find at retail.
Better Built Crown Series Crossover
Steel-bodied alternative. Heavier than aluminum but more impact-resistant, and significantly cheaper. Paint can chip over time.
Lund Aluminum Slim Line
Low-profile crossover for owners who don't want a box that towers above the bed rails. Less storage volume, sleeker look.
JOBOX Steel Site Box
Industrial-grade chest. Designed for jobsite security, weighs a ton, and works as a permanent in-bed installation. Overkill for most owners.
Buyers Steel Underbody Box
Mounts under the truck frame, freeing up bed space entirely. Smaller capacity, more complex install. Great for service trucks.
Kobalt Polymer Crossover
Plastic-bodied budget pick. Light, won't dent, but the lid flexes and the latches feel cheap. Fine for occasional use.
Off-Brand Plastic Bed Box
Avoid. The hinges, latches, and seal will all fail within a year or two of real use. Pay more, buy once.
