We bought our '02 rig in June 2010 from the original owners. It had just under 12,000 miles on the odometer and 48 hours on the generator hours meter. Apart from a rotted out topper on the living room/dinette slide and OEM tires from the chassis build in '01, it was in excellent shape.
The owners were retirees and he had developed medical issues that made travelling inadvisable. We've had good luck with the vehicle - the interior is still in excellent shape. I got a couple of body dings, one is a small circular piece of gel-coat popped off the back bumper when I backed into a neighbor's rhodie bush. The other is a series of scrapes, low down on three of the passnger-side stow-bins that I think will be fairly easy to fix. I got those from a 30" high rock wall while maneuvering into a tight campsite in an Oregon SP.
The one significant issue is the generator. I had cardiac surgery late in 2011 and didn't get out to do the once-a-month generator exercising routine. We never use the generator, always being FHU people and rarely going to places the second a/c was necessary. I'm still investigating that one and may seek prfessional help soon.
Unfortunately, we're finding the cost of using the RV is becoming unmanageable. When we had our first one (a 26' Class C with a Ford 460), gas was around $1.75 and CG fees rareky topped $15 a night. Now gas is up around $4 and it's rare to find even State Parks under $30.
I'll get an appraisal to determine if the flaws are show stoppers and proceed accordingly. We bought the rig from an ad in our local weekly newspaper, but I'm thinking that a consignment might be the way to go. We have a very reasonable consignment dealer in Burlington, about 20 miles away.
