Thank you for all the replies. We are going to look it over this Friday.
We did see what look like delamination or bubbles under the window, but the owner says it's just the photos and there's never been a leak. Not sure about that. If there are any leaks we won't consider it. As much as I like the looks, I don't want to put a ton of money into repairs. Unfortunately, I am not very "handy".
My wife found a 96 Dutch Star by Newmar she's interested in. A class A might be a better option for us anyway as we'll be living in it until this Fall.
