We have the 1998 version of that very same coach. It only had 17K on it when we purchased it. Of course, we have learned a lot in the 2+ years we have owned it. One of those was that we got lucky, it had been originally purchased from the same dealer so they had all of the service records. Some things needed some work - the generator (7Kw Onan) doesn't like hot or cold weather so I just bought a new fuel pump and fuel filter for it, the slide toppers are a bit ragged, added LED TVs, replaced all tires (10 years old,) some of the drawers were in need of some gorilla glue, etc. mostly stuff that comes from age. But everything runs and it was a deal.
All in all that is not a bad deal as long as it doesn't need tires or new awning, etc. and everything works, then you have some room to bargain.
We love the floorplan and she has been very good to us. Best of luck in your search!
