well if you use lengths of pipe as sleeves, and a smaller pipe inside those like a hinge pin. it might be a bear to get loose, though.. think how much fun it is to take a door off its hinges.
pipe hangers, clamps, straps would secure the "sleeve pipe".
i was thinking how cool would it be to just pop legs on the ends of the pipes and tada the camper is standing. then just pull the trailer ahead and away.
