I set off looking at this sort of thing a while back and that is certainly the best I've seen. I did however come to the conclusion that the following issues make a tent or bivi bag the right idea:
1. Unless you have a double adult chair you need pull out/put up sections. On arrival you'd still be building something and there are joints that might leak.
2. On an outfit without reverse gear, your head wants to be in the nose of the body unless you can always find a level surface or are strong enough to push back every morning. This makes the shape of the chair all wrong and puts the weight of stowed items in the wrong place, which brings us to:
3. Where do you put your kit while sleeping? Some sort of pac-safed roll bag would work, but come the morning you are going to have to pile it in your bed space wet or not. Any car battery or spare wheel you chose to carry would need to live in-line with the sidecar mudguard.
I don't think a solution is impossible*, but I think it probably involves a Triumph Rocket or Goldwing and a modified body from one of those pod caravans.
*My technical solution is a sort of car roof box with a port hole in the curved nose. The lid hinges at the rear as the front lifts on gas struts. The gap between the two is sealed with tent material and there would be a zip to climb in and out. Once inside, and unloaded, an inner-tent section would be dropped from the roof section to create the sleeping space. When stowed, the thin plastic base of the inner would act as a a divider between sleeping bag and mat and wet outside bags. For anyone over about five-six, there would need to be a sort of kickout "bellows" to the rear. Does anyone have a small fortune to make one and a bit of experience with fibre glass, as I can't find anything the right size to adapt and concluded was going to cost a lot to make, Or, does anyone know where I can buy an old life raft and what they weigh
