I'll try to get pics one of these days. Some things I've settled on after a couple carpet kit builds:
- I cam straped the side boxes to the built in anchors so they don't bounce around when the center is out.
- I've got just enough space under the bridge to store rocket boxes upright. That still gives enough room above to sleep, although it's not spacious.
- I built the center bridge sections like a hollow door. I did 3 sections, each with (bottom to top): 1/8" ply, 2 x 3/4" perimeter frame, 1/2" ply, carpet foam, indoor / outdoor carpet. The whole thing is ~2" thick, and the dual layers of plywood glued are stiff enough to support 2 people without difficulty - even when, ahem, stressed. They can stack at the front, lay flat on the bed, or come out entirely depending on my load.
- I kept the top-load compartments over each wheel well, but cantilevered the side boxes so nearly the full width of the truck is open at the back. 1/2 tons these days are so tall you can't really reach in from above anyway...
- 2 Therm-a-rest 2" camp rests nicely fill nearly the whole space.
6 total pieces, I can move it in and out of the truck easily myself.
