I have a 6x12 v-nose cargo trailer that I have used a sleeper when hunting. I have been using a cot but that is getting old. I am not looking to install a fridge, stove or any water tanks. Just a full size bed that folds against the wall and some storage cabinets and shelves. Anyone one ever make one into a primitive camper? Any lessons learned? I have plenty of carpentry experience and tools but want to keep it simple.
