Saw an idea I want to look into making but am not sure how it is done. I'm looking at the idea of making a folding camper of sorts that all the sides fold in and lay down on the deck so it is compact for hauling. It's very small (likely full bed size) and for sleeping only. Not a teardrop trailer as I have ideas for that. I saw this and thought the folding walls idea works just how do you do it? Also like the idea of the roof on this project. Any thought?
