The fasteners for the front cap on the motorhome have failed and the front cap is separating from the body of the coach. Safety is an issue because a part of the vehicle is separating from the rest of the coach. We have contacted the dealer where our motorhome was purchased and pictures have been taken. We will be making arrangements for repair with Camping World in Golden, CO. The warning is the sight of the cover on both sides of the unit; the cover is separating from the coach and curling back. Our motorhome is low mileage (18,000 miles and a five year old vehicle). It has been housed in covered storage when not being used so weather and sun have not been a factor. January, 2025 we noticed the problem.
