We've had a few issues with our 2016 25FB25, taken it to the dealer but every single issue we had to redo ourselves.
1. Leak under bathroom cold water sink. Dealer tried to fix by pushing air through the plumbing & tightening fixture. We had to redo ourselves as it didn't help one bit, but taking fixture off & reseating helped.
2. Roof around fantastic fan started leaking, we resealed the vent on top. Suspect storing ours outside in Colorado heat/sun 2nd year caulk corrected. The
leaks can appear anywhere around the trailer but found it after roof self inspection.
3. Bathroom door expands when we travel to Florida/Texas (from humidity) and we can't close the door. Dealer couldn't help, they said they adjusted, but still happens. Called factory, no help, never heard of it. So we'll carry a plane to shave the door next time.
4. Other minor
electrical intermittent issues, but solved them ourselves by tightening fasteners.
Overall we love the trailer, easier to pull, and heat when it's cool, have the extended storage on the front which is amazing.
