Yes, camping platform. I have a 5'x8' trailer that I've put an aluminum frame on top. The frame is 80/20 extrusion 24" tall bottom and top rails of the 1.5" x 3" extrusion. Strong and light. For my yearly camping trip, I use 4x4x8' 3each to support 2 4x8' ply sheets. That is where the tent goes. ( it almost always rains REAL heavy for the festival. I sleep better when dry.)

I want to put HDPE plastic on the sides...aka, marine board. Same basic stuff as cutting boards are made of. not a problem there, other than my wallet gets smaller.
The top...I need a foldable top that I can then fold out to 9'x9' or even 10'x10' for a sleeping platform. I am thinking of a set of torsion boxes. The issue is waterproofing them. Or has anyone tried alternative matierials for a torsion box?
My concerns with plywood torsion box:
Marine plywood is expensive.
replacing the warped sheets will be problematic if the coating leaks.
unit will be stored 300 miles from home most of the year, so maintenance (recoating of exterior of TB) is an issue..
Support legs will be easy, as Unistrut make galvanized holey-tube that telescopes.
Looking in serveralforums to see what ideas might be had. Please let me know!
