I've owned RV's and boats for many years. Why can't the RV parts manufacturers make their plastic parts so they don't yellow? The marine industry doesn't seem to have a problem. I have a 2004 boat and none of the plastic yellows. My TT is less than a year old, and parts are already yellowing, while other parts aren't.
Stove and oven vent yellowing-
Refrigerator cover not yellowing-
Storage door clasp yellowing-
Outdoor speaker...Cover yellowing, base white-
If I could somehow find the names of the manufacturers, I'd email them this post!
Ok...I feel better...anger subsiding...
