I always find it very interesting that anyone wo9uld post in any forum about a issue that is covere3d under some type of warranty? I have3 always gone back to the dealer so that there is a history of the problem, and hopefully the dealer told the manufacture, But in either case you have the history if the problem turns into something big and the dealer runs you out of warranty. I had that exact type of thing happen, that a number of dealers were unable to repair/fix a number of issues I had with a new coach, and by the time I had taken it back to the factory it was out of warranty, but it did not matter as there was a history, and the factory fixed every item better than new.
SO again any time you have an issue with the potential of this (water leaks) just take it back to the dealer and start there first. Good luck and Happy Camping
