OK, I got a link to this shuttle from a friend on this board:
https://greenville.craigslist.org/cto/5318557937.html
The owner is asking $1000. He says the rear brakes need work and all the tires are old. I asked him for the tire size and looked on Craig's List in his area. I can get a set of four used ones with good tread for $150. New ones are only $100 each. He says the engine is a fuel injected 460, v8. He says there is very little rust underneath. I believe him. He seems like a trustworthy guy.
I like that the windows are flat, so I can easily replace them with double-pane windows later. Or even just add my own second pane as I would do in a regular house window. You will notice that he has cut a hunk out of one side, in an attempt to make a vending window. He was trying to make this into a hot-dog food-truck. He gave up and decided to buy a trailer that was already fitted out as a food trailer. I can live with that for now and then replace that span of metal and reinstall the windows, which he kept.
I am seriously tempted to go pick this thing up, sell my car right there in the same area, swing back by to pick up my stuff here in Austin, and then head out to RTR. I will have no gear, no solar, no nothing. But I will have about $3k - $4k after tires and gas and selling my car. As I will be passing through half the country to get from SC (where the shuttle is) to AZ, I can check Craig's List ads all along the way to try and get needed gear on the cheap.
Due to the angular design of the body, I already know that I am going to paint it to look like an original Star Trek shuttle. I could even make inflatable tubes to look like the nacells on the side. They would serve as a great way to keep the cold winds from blowing underneath.
