I bought my America Dream for 42,000 probably paid to much, but have been happy with the quality of the coach. I have had nothing but problems with finding quality people to work on it.
I have given up and am doing the work myself now, which is something you will have to think about on an older coach.
The chassis will be fine so long as it was maintained, it is all the small stuff that will have to be looked after (refrigerators, heat, A/C, generators etc.
Take a look at my
projects threrd.
I am not saying don't do it, I am saying be prepared to have some work to bring it back. So far as I am concerned old coach are far better built than the newer ones, just read about all the problems people are having with the quality in the newer coaches
