My Beaver Patriot from roughly the same era with two slides has had some issues, the biggest being the lack of a cross member on the frame in the rear. We repaired it. Other problems are no different than newer or older coaches. I have talked with other Beaver owners from that era who absolutely love their rigs. I think things were a bit spotty but those issues should have been worked through. The Magnum Chassis drives well, we have the CAT 330 and have a bit over 25000 on it. We did replace the original Bilsteins with Koni's as the Bilsteins lost their seals. Our chassis has eight airbags and 2 shocks per corner. Woodwork is excellent. We looked at a 2008 DP and were disappointed by the woodwork with latches almost falling off in my hands on a brand new coach. If your rig has the Hurricane hydronic system it will need service every year without fail. I guess what I am trying to say you could do a lot worse. I'd have one of the pro's look at it, drive it and let you know what they think. We updated the satellite system as the Datrum System is no longer made. We are going to replace the couch and put in a larger flatscreen but I consider it to be elective surgery.
Good luck with whatever you decide and let us know.
