We have a 2007 Forest River/ Rockwood that we bought new. It also had a design issue with the roof when it was new. After taking it to the dealer a couple of times, I contacted Forest River & they were very helpful. We arranged a time & they sent someone to our dealer to take care of the problem where the dealer couldn't get it taken care of. I would suggest contacting Forest River for some assistance in getting this taken care of. Even though it is a documented issue on your camper, it gets much harder to address once it is out of warranty. I would push harder to get the factory rep involved ASAP.
