Goals for this build:
Light enough to pull with the old Dodge wagon.
Insulated enough for moderate Oregon temps.
Sturdy, and hopefully long lasting construction.
I've made several drawings, modeled it in 3D, and I'm a few days in to building the base and ledges now.
I'm using 2x2 (with the occasional 2x4 used in critical areas) framing with 1.5" EPS foam and plywood sandwich. I've used 1/2" and 3/8" plywood so far to get a sturdy base. The rest will be luan, maybe some 1 ply, and I'm going to waterproof with canvas / titebond / paint. I also have small CNC router so I plan on adding some cool appliques later in the game.
The plan is to use a harbor freight trailer, this may change. It's a 4x8 base with 12" ledges. The side walls will be 4x8 similar to the floor but lighter weight, and angled out 7 degrees which puts the bed height 3ft off the floor.
