Finally got around to working on the bunk. Our bunk will be 4'6" wide so we can use a standard full sized futon mattress on the bunk. Prior to mounting the lower end panels, I used one as a pattern for the bunk supports. The bunk supports were shortened 3/4 to account for the thickness of the benches. 1x2 strips were attached along the upper edge of the bunk support to give me something to attach the bunk plywood to. A small piece of 3/8 plywood 2' wide covers the gap between the benches. Next I mounted the other bunk support 2' from the other. That leaves me 6' on the benches for sleeping areas. Now the caravan can sleep 6 easily. Both bunk supports were notched for the 2x2s that support the bunk. The bunk is not finished yet. I still have to add supports to the 2x2s. We couldn't resist putting the tarp on and seeing how the caravan will look covered. It actually felt much roomier inside once the cover was on.
