Note that vinyl shrinks with age. As many other report, the arch just above/behind the drivers/passenger doors on Class C's pull out over time due to this shrinkage.
Rather than replace the length, I pull it up from the bottom, then add a small piece below to complete the fill, like this:
The small piece was a tad narrower, so it didn't bulge out like the original, but still did the trick. I added an external stainless screw to hold everything in place.
As others report, seal each screw head before inserting the vinyl strip
For those of us who use our rig occasionally over the year, a big part of preservation is storing your RV under a solid cover or in a garage/shop to keep it out of the elements. It's not possible for many folks, but it sure makes them last a lot longer.
