We have the same issue on our Keystone Raptor front cap. We purchased a warranty for the Tires, Interior fabric and exterior protection back when we bout the 5er new. When I noticed the fading I called the warranty company and there were several things they wanted, pictures and an estimate. At the end of the day its in the shop getting the front cap fixed under warranty!!
We shall see how long the new cap will last. I have been thinking about making a cover for just the cap as it faces south while stored in our driveway. Has anyone done this? Here are a few pictures of the fading and sticker delamination.
