After hours of drawing amd measuring I now see that it is impossible to make a camper with a nice shape and still retain a 24" bunk. On the front it encroaches on the door and the back would be too curver for the top bunk to have any space.
I am now considering something like a Rimple to maximize interior space and be able to install a bunk in the back. 5 1/2 X 8 and able to sleep 4.
Another thought was to move the door more towards the rear if I moved the axle. Why do people move the axle? I was assuming it is because there will be a heavy galley in the rear, but I will have no galley. That would maybe get the tire back far enough so that I could make a bunk in the front and not encroach on the doorway. But I think I should leave it for the correct center of gravity/tongue weight.
