Build # 3 will start tomorrow. I sold build #2 a foamy because I had too many new ideas. So best to start new. I programmed the inner wall (3/4" CDX ply) supports, the outer, and inner skins, ( 7/32" plywood) and the insulation (3/4" ridged board insulation) I'm using the same lightweight A frame set up from build #2 (2" by 1/8" steel angle) and the Torsion half axles. What will change is the way I am building the support frame on the bottom. We all get the standard metal frame from Harbor Freight, Northern Tool, or make a metal frame ourselves. What if we integrated the support frame into the walls instead? and instead of steel, we use wood. I am planning on using only 3/4" plywood as the base frame with a 3" tall wood frame along the outside edge. The trailer is only 4' 6" wide by 8' long, so just a basic sleeping trailer, no standing.
More to come.
