I bought my Airstream because I thought this was supposed to be fun. The day after Christmas I had a blowout...no spare and absolutely no knowledge of what to do with it if I did.
I called Good Sams. Best One Tires fixed it and I drove another 2,600 miles with no problems. Fixing it it cost me $400. I tipped the guy from Best One another $100 because it was 15 degrees on a Sunday night.
It takes money to play this game. If you ain't got it, forget it.
