All the screws were there when I replaced that vinyl trim on my Class C a couple of years ago. The problem was that while the trim was in OK condition, the motorhome had been built in July in the heat of the summer, and the trim pulled super tight before being screwed in at each end. Every winter in the cold northeast it shrank and pulled out of the track. As it got older, what little elasticity it had got less and less, and eventually it just wouldn’t stay in. This led to a couple of times it completely coming out of the track while driving, coincidentally each occasion being in busy conditions on I-294 going around Chicago. Fun times to pull over and pop it back in by hand.
When I replaced both sides, I did it in 50-55 degree weather, and did not stretch it at all. Holding up fine. The original install was yet another example of the fine workmanship we’ve all experienced.
