A friend of mine had an old,old trailer, All rotted out. He'd put pieces of plywood on the soft spot on the floor and glued a blue tarp on the roof. When he got to where he was going to camp he drove stakes in the ground and then tied ropes from the trailer to the stakes. Then he adjusted the ropes until the door didn't bind any more. Poured himself a rum and sat back. he enjoyed camping as much if not more than the guys with the $100,000 motor homes.
