Fleetwood Jamboree 29V

We are starting to look at various Class C's around 28 - 31 ft. and are using the RV Consuemr Group ratings as a guide (not our only source, but with the overwhelming amt of choices out there, it is nice to get some idea on various issues . . .). One unit that is rated acceptably in our opinion by them is the Jamboree 29V. We are looking at 6 years or newer and have been coming across quite a few used 29V's in this area (Michigan). Anybody know if it's just a popular unit and a lot of them are made, or have there been problems with them and that's why there's quite a few on the used market? Right now we plan to check on a 2001 and a '99, but are open to other recent years as well. Thanks for any response.
