What a great build this is! I hope you enjoy it with the family for many years to come.
I am building a pop-top truck camper and am planning to galvanize the steel frame, then use VHB tape and aluminum sheet to skin it.
How did you protect the steel frame from rusting? Painted, powdercoated, galvanized it? And how is the aluminum skin holding up? No buckling on a hot day because the aluminum expands more than the steel frame? And no problems with corrosion (with the steel and alu combo)?
Sorry for all the questions. Did I say great build already?
I hope mine turns out half as good, that would be more than enough for me!
