That's a hard one to call. Really depends on your willingness and ability to do repairs yourself. The Thor Residency was a good coach but at that age, previous care and maintenance is everything.
A few comments:
> New roof - actually a new roof or just recoated with something? How much water damage occurred before it was re-roofed/coated?
> Tires at 6 years are actually nearing the end of their useful life on a motorhome. If it is on the Ford chassis, they are only 16" tires so replacements are reasonable.
> Front roof air dead - the roof A/C is pretty much a sealed unit and not usually repairable unless it is something simple like a bad wire connection.
Anytime you are shopping at that age and price range, it could be a good motorhome with a little elbow grease or a complete money pit. No way to predict. I'm not trying to discourage you, just saying be prepared and keep your eyes open.
