We have a 2013 Solaire, purchased new last fall. I would rate the quality as comparable to our last camper, a 2006 Rockwood Roo. We've had a few fit and finish type of issues that have resulted in two trips back to the dealership for warranty service, but nothing I would consider major such as water leaks or slide out problems. On the plus side we love the floorplan and it tows great, especially considering it's 34 feet long.
Time will tell. Good luck in your decision.
