Those ford teardroppers are very cool. Beautiful designs.
I could use conduit for the frame, and instead of sheet aluminum I could use a light gauge galvanized sheet. The last galvanized sheet metal I dealt with was very light. I wonder what gauge would be sufficiently strong, but not too heavy? My buddy could hook me up with a lot of galvanized...his friend owns an hvac company.
As well, if I used conduit or 2x2s, what would be the best method to fasten the skin to the frame which would not leak? Caulk under every screw? Spot weld? I have used self drilling sheet metal screws with great success before when I attached 1/2 a VW bus to the top of my old van. That was a great project. VW on top of a 1/2 ton van. So fun!
