Truck Tool Box For Under Tonneau Cover Buying Guide
Finding a truck tool box for under a tonneau cover means low-profile designs for hidden storage. You want to keep your gear secure and out of sight, but you also need your cover to close flat. That combination is tricky. The wrong box leaves you with a bulging tonneau or wasted space. Let’s look at what really matters when you shop.
Height Clearance
Check your tonneau cover’s clearance first. Roll-up covers usually need less than 2 inches of space above the bed rails. Folding covers might require more. Measure the gap between your bed rails and the cover when it’s closed. If you guess, you’ll end up with a box that sticks up. That ruins the whole setup. A low-profile box should sit flush or slightly below the rails. Simple rule: measure twice, buy once.
Mounting Style
Some boxes clamp onto the bed rails, others bolt directly to the bed floor. Clamp-on models are easier to remove if you need full bed access. But thay take up headroom that your tonneau might need. Bolt-down boxes sit lower but require drilling holes. Think about how often you’ll take the box out. If it’s permanent, go with bolts. If you swap gear often, clamps are quicker. Don’t forget to check if the mounts interfere with your cover’s seal.
Material and Weight
Aluminum is lighter and resists rust, but it dents easier. Steel is tougher but heavier—and rust can be a problem if the finish chips. Diamond plate looks rugged but adds weight. For under a tonneau, weight matters because you might need to lift the box out. A 40-pound aluminum box is manageable. A 70-pound steel box is a back strain. Also, think about weather. If you live in a wet area, go with aluminum or coated steel.
Lid Opening Direction
Does the lid open toward the cab or the tailgate? Toward the cab is standard, letting you grab stuff from the side. But if your tonneau cover rolls from the cab end, that lid might hit it. Some boxes have lids that open on both sides. That helps, but they cost more. Picture yourself reaching into the box while the tonneau is half-open. You want easy access, not a wrestling match.
Frequently Asked Questions About Truck Tool Box For Under Tonneau Cover
Can I use any truck tool box with a tonneau cover?
Not all tool boxes work under a tonneau cover. You need a low-profile model. These boxes sit low in your truck bed. This leaves enough space for teh cover to close. Check the height of the box first. Measure your bed’s depth and the cover’s clearance.
What types of tonneau covers work with a tool box?
Roll-up and folding covers are the most common choices. They are flexible. They can fit over the box if you have the right setup. Hard covers, like retractable ones, may not work. They need a flat surface. Always read the cover’s manual. Some brands offer custom-fit options for tool boxes.
How do I measure for a tool box under a tonneau cover?
You need two key measurements. First, measure your truck bed width. Second, measure the height from the bed floor to the cover’s lowest point. Subtract a few inches for safety. This tells you the maximum box height. Also, check the box length. It should not hit the tailgate or cab.
Will the tool box block access to my truck bed?
It depends on the box size and cover type. A slim, cross-bed box takes up little space. You can still reach items on the sides. For full access, consider a sliding or hinged box. Some models tilt forward. This lets you get to stuff under the cover. Plan your setup based on what you carry.
Do I need extra hardware to install it?
Most tool boxes come with basic brackets. But you might need adapters. These help the box sit flush under the cover. Some tonneau covers have special rails. You may need to buy a mounting kit from the cover maker. Always check the box’s installation guide. It should list required parts.
Is there a weight limit for the tool box?
Yes, each box has a max weight rating. Check this before loading heavy tools. The box itself must be strong. Also, your tonneau cover may have a weight limit. Heavy boxes can damage the cover over time. Stick to light tools or use a box rated for heavy loads.
Can I still use my truck bed for other cargo?
Yes, but it’s tighter. A tool box under a cover reduces vertical space. You can slide flat items like lumber on top. For bulkier stuff, you might need to remove the box. Think about your typical needs. If you haul big loads often, choose a smaller box or a different setup.
