2013 Gazelle G-215
Ours went to the factory in 2012, the year we bought it, for extra bracing because of soft spots by the bathroom door. They removed the gray tank and added some reinforcement. It was soft where 2 floor panels seemed to meet. Last year we noticed in August that the entire bathroom was real soft and when I put a small hole in the underbelly, it was wet. Dealer could find no leaks anywhere but said the floor was real bad. The worst he had ever seen and could not fix it there and have it be right. The unit went back to the factory (out of warranty) and they fixed everything at no charge. Factory rep told me it was built wrong from the beginning and they found other spots they repaired too. I could tell they removed and replaced all of the bottom trim around the unit and found lots of extra sealant in places it wasn't before. They fixed the bathroom by dropping the black tank, removing the rotten luan on the bottom (foam and top luan were OK) and replacing it with 3/4 plywood and resealed everything back up. They also had it open underneith for about a week with fans blowing to make sure it was dry. The only cost I incurred was picking it up at the factory because I wanted it home before anymore salt got on it like the first factory trip. So far so good. I did seal a few more things under there myself just to be safe. Ours is a Gazelle with the rear bath and the slide that has the couch, no dinette. The dealer and factory were very good and corrected the problem. In general though, I have grown very suspicious of these floors and would rather have the extra weight and real wood under my feet. With the 3/4" under the bathroom, I can tell the difference that it is now more solid than the rest of the coach. I am tempted to put a piece under the main walking area just for the added stability. Our 20 year old pop-up had just a 3/4" floor with no plastic underbelly and it was as good as the day it was built. Good Luck.
