As this thread demonstrates, there is a lot to be dissatisfied with in dealer customer service. I suspect this is true not only with Forest River dealers, but with the entire industry.
Trying to "force the issue" with dealers is usually a fool's game, although there are exceptions.
After a fair amount of experience with this issue, I have concluded that Forest River customer service (Coachmen division, in my case) tries to do their best, in a very difficult situation, especially if you establish a good personal relationship with them. Contact them to go to bat for you, if, as usual, your dealer is unhelpful or incompetent, or both. Don't expect perfect solutions.
For my part, I am eagerly awaiting the expiration of my one year warranty (sounds ridiculous) so that I can fix small things myself, and get an extended service contract so that I can bring it in to a repair shop of my choice who will welcome my business, rather than treat me like a disease.
