Thanks for the suggestions. One of my primary goals is to design the back more like a building would look, less like a vehicle. The roof line (including the part over the cab) is a uniform arc. If I altered the part over the cab, it would sacrifice the uniformity and, when set up, would look rather odd (I think). There may be a way to do it and you have sparked the idea. I also like your idea of having the top seal like a pop-up camper. I have considered the sealing issue and it is a major problem. I remember a hard sided pop-up that my parents had when I was young. It might be an option and would solve several problems (including the weight of the massive hinged roof).
If you look at the back you see the windows in the doors and windows on either side. The primary bed (and a dining/sofa area) would be at the back. The bed would actually block the door in back (that is why I have the second door). I want the bed there because I want the views. It isn't ideal for several reasons, but then this camper is just 11 feet long inside so there are no ideal solutions. The slide out/tip out option might give me a better solution - if not for the primary bed then at least a better choice for bed #2.
The rounded roof edge would be much better aerodynamically but much worse aesthetically...I think. It is a very difficult choice. Is it a vehicle that becomes a house, or a house that moves? Where to a draw the lines of priority? For me it is first a home. I live in it for so many months that it has to be comfortable.
I have modified the design to drop a bit lower. This reduces the frontal area and the drag.
This is probably the most it can be reduced in any dimension. Other than this it will just be mods in things like the way it folds down on the sides.
Thanks for the advice. It has helped.
