Pictures didn't come through but it sounds like a pretty big issue. One major advantage you have is living so close to the Factory Service Center. I would call CS and set up an appointment with them. The labor rate is only $100 per hour and they know the coach better than any dealer...plus, they have everything on hand with no major waiting as in most dealer repairs. My experience there was outstanding!
