After gary brought up the edsel camper earlier i found this forum thread with all kinds of different camper vehicles i thought were interesting.
Recently my dad called me to see if i can find him a pic of the roof mounted 5th wheel trailer for a car. I had posted the same one he was talking about here in the garage way back so knew exactly which he was talking about. He needed to prove to some guys at the tavern that they really did exist. So he won that round. lol
This is the forum link.
