As far as I know, Any dealer which sells any brand of a Forest River Parented RV's can do warranty claims, if they choose to. A rockwood dealer can fix a Surveyor etc ... The factory will make the necessary knowledge and aprts available and guide them on repairs. They do not have the be selling that particular sub division of RV's to be able to work on them.
That is what I was told and heard from other dealers. So if the are any dealers at all in your area which sells any Forest RIver product, you should be able to approach them and ask if they can help you.
If you bought from Jeff Couch, they would be happy to put you in touch with the warranty administrator when you are in a bind like this. I could not get any dealer work on my unit and I was routed to the factory and happily lived ever after
