Tonneau Cover
A Cover Sized to Your Bed, Not Your Badge
A tonneau keeps weather off what you are hauling and keeps it out of sight at a gas station. Every listing on this page is tied to a bed length, because one truck model is often sold with two or three different boxes behind the same cab. Measure before you shop and the rest gets easy.

Measuring your bed
Put a tape measure inside the bed, from the inside of the bulkhead (front wall) to the inside of the closed tailgate. Round to the nearest inch — a 69" measurement is a 5'8" bed.
Bed length is measured inside the box, not along the outside of the truck.

Measure inside the bed, from the bulkhead to the inside of the closed tailgate. That number, not the badge on the fender, is what fitment is built around.
Rough Country, Bestop and Westin account for most of what is listed, with Steelcraft, Rugged Ridge, Rampage and Smittybilt filling in around them. Covers differ in how they open and in how much of the bed you get back when they are open, so read what each listing says about access before you settle on one.
Two practical things people forget. Check that the cover clears anything already in the bed, like a toolbox or bed rails. And think about whether you will be opening and closing it alone, in the rain, with your hands full. Our stores fit covers if you would rather have it done right the first time.
Common Questions
How do I find my bed length?
Measure the inside of the bed from the bulkhead to the closed tailgate, then match that to the nearest listed size. Trucks are commonly sold with more than one bed, and the name of the cab configuration tells you nothing about the box behind it. Every cover here is listed by that measurement.
Will a tonneau keep my gear dry?
It keeps direct rain and road spray off, which is most of what people are after. No bed cover seals like a trunk, though, because beds have drain paths and tailgate gaps by design. If you are hauling something that cannot get damp at all, put it in a sealed box under the cover.
Can I keep my bed liner or toolbox?
Often yes, but it depends on both pieces. Rail-mounted covers and over-rail liners can conflict with each other, and a toolbox usually means you need a cover built to work with one. Check the listing, or bring both model numbers to a store and let someone confirm it before you order.
