How many times do you see happy campers, driving off into the sunset, with tv aerials waving around like flagpoles, and sun roofs open to the elements. If they can’t do basic travel checks, imagine how confused they will be with slide outs and slide ups.

looks like the top deck has folding/flexible walls so just a big pop top but for a roof solid enough to walk on & second roof & sides may be a bit too top heavy but often these off the scale ideas prompt smaller advances
