DIY Tonneau Cover
Spent a couple hours last night building a bed cover, since they're calling for snow this weekend in Maine and I won't have a garage to put my truck in for a couple more weeks I decided it was worth it to build something so I wouldn't have to shovel out my bed.
I built a frame out of 2x3 studs that follows the dimensions of the inside of the top of the bedrails, and then screwed it to a sheet of MDF. With my 5.5' bed and tool box I have in there, the 4' wide sheet of MDF was the perfect width; I just had to cut it to length.
The frame slides under the 'lip' on the toolbox, and when you slam the tailgate shut, it sort of wedges it into place. I took a couple eye bolts and screwed them into the frame so I could use tie downs to strap it down to the hooks in the bed but It's in there tight enough that it probably isn't necessary.
I ran a router around the top of the MDF to make it look a little more finished.
I used bedliner paint to finish it and it came out... less than satisfactory. Next time I'll buy the roll on stuff instead of the spray on stuff.
Total cost? About 50 bucks.
