At some point, maybe 2016-17? (I don't remember exactly) Keystone began to paint the front caps with regular automotive paint? Prior to that the caps were very prone to fading due to sun. My 14 experienced it in the first year, the SM caught it and repainted it. In 4 years afterward it was not a problem The back wall? Pointed to the sun it will fade and oxidize quickly. I don't know an answer other than to keep it out of the sun or always wash and wax it regularly with good UV products. Lots of threads and comments on that.
