I finally got tired of just sleeping on a mat in the bed of my truck camping so I built a sleeping platform. I built it 70x42.5 inches. I used ply wood, some foam used as a mattress topper, a 2x4, some liquid nails, screws, staple gun, and some carpet from lowes. It took me about an hour to complete. I think it is going to work out just fine for all of my camping trips and it was all built for under 50 bucks. What do you guys think?
