Cool, thanks bka, I will check those out. I had considered ears for the solar panels, welded to the aluminum sheet before I install it. I think it could be a good idea if done right.
I wanted to share a construction technique I tried that worked the first time (go figure). I needed a curved section for the front of the camper, so I decided to try hand bending some 1x1 16 gauge tube instead of going some more complicated route. I needed a 19 inch radius on the inside and 20 inches on the outside. I knew the metal would spring back a bit from whatever bend radius I chose, so I guestimated and jigsawed a wood form with a 17.5" radius. The final bend came out to within 1/16" of the correct bend (measured by the chord length connecting the ends of the arc). Pretty neat, huh?
