hey all, many thanks for all the responses. I can't tell you all how much I learn here everyday.
In the end, i held off on the coach. I don't mind paying good money for an inspection, but I'm in Florida, the coach was in Texas, and the salesperson was telling me the dealer wouldn't put the coach through their shop to inspect it. They wanted me to do the inspection first.
Ultimately, I wasn't willing to do that. I wanted some assurance from the dealer that the coach was examined without me putting my own money into it sight unseen.
