I would require the roof to be lifted. I would not want to be in a place where I could not stand up straight. Might be a good way to avoid property taxes. I wonder if it would require city approval if I bought a lot/land and put a bus on it. Maybe more than one bus. and connect them together. I would want plumbing as well. That would probably require permits. I guess I could use solar for power.
Or maybe one bus for the living room, one for the kitchen/eating area/pantry, one for the bathroom/closet, and one for the bedroom. 4 buses connected together.
