Thinking ahead about the roof materials since we may go ahead and put on the roof after the steel frame is finished (will add strength and also the roof is simple (zero holes or openings).
We intend to make the roof outer layer one piece, probably 0.050 or 0.062 aluminum. Under that will be two layers of 1/4" marine ply, bent around the curve section of the camper front.
I can sikaflex and/or screw the ply to the steel 1x1 and 1x2 roof truss members, but how to attach the aluminum skin to the ply? That would be a hellava lot of sikaflex (messy and expensive) and way overkill.
You guys have any good ideas? We want the roof to be walk-on-able.
