I'm confused. You had to have your coach repainted because you had a flat tire? A good tire company would have been able to replace the flat you had the next day. Unless you have some ridiculously unusual tires, they just order the tires from their supplier and get them in a day.
Your insurance should cover some of the losses to the contents. In fact, the shop ought to have some insurance liability for damage to a vehicle while in their possession.
If you're full timers like you say, how could you go without your house and your clothes for five months?
