Wow, your story tops mine. See my Keystone story here:
Very Dissappointed with New Keystone AlpineThere is no point going to the factory, they will not repair it there. I speak from experience. Calling is no help either, they will tell you to open a warranty claim through a dealer. They will listen to your problems and take notes but will only review your claims via a dealer.
It is my impression that Keystone is too big to care these days. Since the latest RV boom, they are focused on throughput and quality is far down on their priority list.
