4 1/2 hour drive to look, not bad. I did 8 hours, each way, three times but got a very good deal on an 2006 31D.
The low mileage can be a red flag. My concern would be the owners used it one season, put in outside storage and there it has been sitting ever since untouched. At 9 years old the roof seals are a big concern. If the coach has a musty smell you'll need to look deeper for potential water leaks from failed roof seals. A hair line crack in a dried out seal will let a lot of water in. Check for delamination around the below floor storage compartment doors. If the fiberglass is soft, flexible, bubbled or has a hollow sound when tapped you might want to look elsewhere. Check the windshield curtain for water stains also. Lack of chassis continuous maintenance is a concern but recoverable. Same with the generator. Tires, if original, will needed to be replaced.
If the coach has been stored inside it should be OK concerning water leaks but not for long if you make the purchase. Use the cost of tire replacement and catching up on missed maintenance to your advantage with a price offer, maybe $40K or so, and let them counter. If the coach has had water leaks you might want to move on.
