I actually have a strong aversion to attempting to camp in any city. I live on the remainder of an old sheep ranch in the coastal mountains of NW Oregon. I'm parked in my driveway, on the grid, with satellite TV and internet. Not exactly roughing it, I know.
My old house began leaking some years ago, and after falling off the roof several times I decided to let the roof alone. The house has molded pretty bad so I've been living in the bus the last couple years. Obviously I don't have storage issues, with a house as well as second and third buses to put things in.
This was my first time at insulating a bus. Hind sight is always 20/20, so at this point I believe I could go through the same process with much more confidence the second time around. I recommend getting the interior stripped out as fast as possible so the walls and ceilings can be insulated. I moved out of the bus and lived under a tarp for a while last summer to accomplish the insulation quickly. For most build projects you can slide your personal possessions to the front or rear in order to get work done.
Ideally if I had a hitch and an enclosed utility trailer for tool and materials storage I'd have been much better off. Shuffling everything in the bus forward and back, left and right gets tiring quickly. There is light at the end of the tunnel.
