The transfer switch on our 2013 Winnebago Adventurer was noisy. It was hard mounted to the storage cabinet wall. I stopped at Lowes and bought several rubber washers about 1/4" thick. I loosened all the mounting screws and removed them one at a time. With a screw removed and the remainder loose I slipped a washer between the switch box and the cabinet wall, then replaced the screw. When all the washers were in place I tightened all the screws. No more noise transferring through the cabinet into the coach.
