It is hard to say, on a 11 year old 5r, it will all boil down to how it was cared for. It will be very important to look for water damage. We use to have a great library resource with things to look for, but this site is undergoing a new software installation and the library is not up and going yet. If you are uncomfortable, most of us highly encourage you hire a professional inspector to look it over and give advise. As important as buying the 5r, what are you pulling it with? In general, RV salespeople are not good sources for knowledge, think along the line... used car salesperson, tell ya what ya want to hear. Good luck, hope it works out. If you have more specific questions don't hesitate to ask.
