Howdy, I've been hanging around the sidelines here for a while and gotta say this is one of the most informative and polite forums I've ever seen. Thanks for that.
I am just in the planning stages probably using a 4x8 tractor supply trailer that I already own. I have also been scouting around at Tiny House forums and have seen some neat little houses with thin corrugated galvanized shed roofing (the type Lowes and HD sells). Has anyone ever experimented with corrugated metal for sides and / or top of tiny trailer?
