Wow that is way cool. I was just looking at that material. Did you just mount it up next to the existing gutter above the awning? I am glad to see it has been there for 8 years too because it is mounted with 3m tape. I am going to order some. I was thinking black as well as i could run it down the side of the windshield rubber a ways.
Yes, I mounted one piece above the existing awning. The way my awning was installed it contributed to the problem. If there is a trick, it is to watch the water flow pattern on your coach and install the gutter where you need it.
I've used the gutter in two other places. One you can see in the picture. I put an "eyebrow" above the windshield to minimize water flow over the windshield because I was getting black streaks.
The other place is over a bedroom slide. Even with Monico's help under warranty, there could be a rug wetting leak. With observation I noticed that, depending on wind, rain intensity and levelness, a small river could flow off the roof and find its way directly to the seal. I put a gutter in an eyebrow shape over the slide to redirect the roof top flow away from the seal. Winnebagos come from the factory with gutters!
