Spent two days both looking at the unit and talking to many service people. Then went back and looked again. The front three feet of the roof is loose I suspect it has been billowing down the road. One real (to me) good service guy with 38 years experience sent me back to look for the root cause of this and someone has been pretty active with a caulking gun all around the nose. There is also a defect/crack in the side at the front of the left side window going on a 45 degree angle to the front. My "little voice" is telling me not to buy this as it may be an issue. The roof is 12 years old and the tech tells me a life span is around 13 years.
