I may have posted this before.... I have a light weight utility trailer with expanded metal flooring and ramp/tailgate... with the ramp vertical, a pair of 2"x2" ridge poles to the front railing can support a plain "blue tarp" held in place with 8 bungee cords... a folding chaise lounge in the bed, mosquito netting, optional poncho liner and I'm in pretty good shape... for extended use a couple of 4'x8' sheets of plywood "C" clamped to the sides for a little more privacy
