I bought my 3670 in MI at Gellette RV and had some things that had to be done in Alabama over the winter and called a dealer out of Mobile AL. told him of my situation and he was more than willing to do the warranty work that needed to be done. He bent over backwards to help me out. By the way, it was Johnny's RV Service in Theodore AL. They also offered to let me stay in there lot overnight if they didn't get all the work done. So the answer is yes, some will do it with a smile. Maybe others might not. But so far I have been pleased by the dealers and Heartland. Very good unit, and pleased with my purchase. We are staying in this fulltime, so we are puttting it to its task.
