I talked to the dealer repair folks and they are not sure either. However, they are so swamped right now with the snow birds, I'm not sure if they gave it much thought.
However, logically thinking, in order for the sound to be produced, there MUST be something vibrating. In order for something to vibrate it MUST be not as secure as it should be. Ergo, I MUST check any and everything outside of the RV because something is causing the noise. How's this sound?
