Fuzion Trim Issue

Had to replace all of the plastic trim that goes in the channels on the whole Toy Hauler. Being as its a 2013 that we purchased new just over a year ago and it it stored in a covered spot I'm shocked that it was literally falling apart on our recent trip to Colorado. Every piece with the exception of the piece that runs from side to side under the front by the generator was cracked and broken. Replaced about 120' of it. The worst part seemed to be the rear which probably receives the most sunlight but probably only 2-3 hours a day and morning when its cooler so regardless never had an RV that needed it replaced so soon and never had to replace it ALL.
