Consider joining
RV Consumer Group. While Some folks don't put much stock in their info, they've been rating RVs for over 20 years, indicating that many people do. They provide ratings for new and used, going back 10 or 12 years, which is helpful now that the "old" new brochures have long flown off the shelves. Membership does cost. But, relative to the overall cost of ownership of a camper, it's a paltry sum to have all that info at your finger tips. In addition, it's a time-saver while pinpointing your needs. Not the only source of information, but a pretty darn good one.
