It is not just the manufacturer, of the bay doors you might have problems parts from. Our Mh was just two years old when the slide stopped working. The dealer hot wired the old motor and it was not the right motor either. It took a few weeks to get it. Fleetwood at the time now American Coach called the mfg and they took time to build the motor. No one stocks parts any more. It might be good for inventory taxes but it is terrible for Customers and Customers remember the next time they buy. Same with Son's Soltice. they had to make the door as all the doors they were getting were going to the car production line. Somehow someone interveined and they pulled one from the line.
