Yes sleeping, Well, whole host of reasons..... My primary is because I am a fisherman. I use the camper for prolonged periods off the grid and want my truck free to shuttle my drift boat (in the truck bed) at will up and down river from where camped. To get through smaller holes in the bush for river access without damaging camper, solar panel or vents on over-hanging trees. There are others but this is primary. Any experience? I have been spiral staking and roping the door end. I was just wondering if others have better solutions. Though I have never done it, I would be interested in urban paved solutions too for an extended stay somewhere.
