DIY F150 Tonneau Cover

Step 1: Description:

My truck has a toolbox and is only a 5 1/2' box and as such, the commercially available pickup bed covers are expensive and require the purchase of a combination toolbox and cover. They cost above $500, and I am cheap. Also I am an engineer and design stuff all daily. After some research, I decided to make my own. And make it look like a purchased cover. Total cost $80, $21 of which was the coating.

I made it out of 3/4" exterior grade plywood that I purchased from Lowe's.


(1) 4x8 3/4" exterior grade plywood or Marine Grade if you can find it (not at Lowe's or Home Depot) $33

(2) C-shape wall brackets for adjustable shelving. $10 each

(12) #10 x 3/4" metal screws, flush mount ( I only used needed 8 screws total, depends on length of rail)

1 quart of rust-o-leum truck bedliner coating, $21 walmart

Step 2: Measure Three Times, Cut Once

On my truck, the distance between the bed rails was 62 3/8" (to provide some clearance I cut mine at 62"). And the distance between the toolbox and tailgate was 45 1/2". So, I only needed one 4x8.

I decided to create two panels, each measuring 62" x 22 3/4".

I had Lowe's cut my 4x8 (easier than hauling and then setting up my tablesaw).

First Cut: Cut the 4x8 to a length of 62". Save the smaller piece for a future project.

Second Cut: Cut the 62" to a 22 3/4" width

Third Cut: Cut the remaining 62" piece to 22 3/4" width.

Fourth: Save the remaining 3" x 62" piece for use to support the seam between the panels.

Step 3: Install

Cut the C-shape bracket to length. (For me, 45 1/2")

Attach the C-shape brackets to the bedrail with the metal screws. The brackets have screw holes every 10 or so inches. Use clamps to hold them in Place while you install the screws at each end. I installed the brackets to be flush with the top of the bedrail.

Cut the 3" x 62" board in 7 equal lengths. And screw them to the underside of the each panel. Stager the boards on each panel in this way the seam is supported.

Step 4: Paint

With the bedliner coating sanding is not required, just make sure the wood is clean of sawdust. It takes about 2 hours to dry.

Use a small 3" whinnie roller with a short nap so that the roller doesn't absorb much coating.

    The final product looks good but there's not enough information here... what is a "C shaped bracket" and where is a photo of it? Are you referring to a wall-mounted adjustable shelving leg (or standard) - with a channel shape? Personally I would find it awkward to handle a piece of plywood after pulling it out... never mind two... especially with those staggered edge pieces. The flush-mounted result is great though.

    How has it held up, has it sagged at all?

    Also, how does this hold up against weather? Rain/snow. I live in FL where it's either 80deg plus sun baking, or hurricane rains.
