My 2014 Winnie class c leaks, and has done so, off and on, since our first trip. The factory and various dealers have been of little use in stopping it permanently. I have spent about $3200 total since new for leak tests, then repairs. I have noticed other brands and I think the ones that the top overlaps the sides leak less.
This was our first Winnie. I purchased it because of owner's testimonials. Maybe I purchased the only "lemon". Irregardless, I may trade in the future but it won't be for another Winnie. Just my "two -cents" worth.
