I don’t have any pictures of it put up, but here’s an earlier post about it:
Here’s a picture of the channel on the camper.

Don’t make the same mistake I did and use two pieces of awning track. You can get 9’ sections from Sailrite.com . I had to seal the gap and it took several tries. Also, Sailrite sells two different Keder strips, one is woven cordura around a solid, flexible poly type core. I used that one, which may be wicking a bit through the woven cordura and has needed several waterproofing applications. The second kind is a molded HD rubber like material. It might be better, but harder to sew.
The awning strip/c channel on the awning is very conveniently built in to the bottom of the mounting panel of the awning. Unless you have that on yours you’d have to find a way to attach the gutter to the side of your awning. I suppose velcro could work, or Sailrite, again, also has a flexible awning track they sell that might work if you don’t have a solid surface that you can use the awning track on.
Also, look a AluCabs Shadow Awn 270º awning on their website. They (used to?) sell a gutter for that awning. It’s where I got the idea. You might be able to adapt that one?
Whatever you do is worth the effort. The gutter makes the camper/tailgate waaaay more liveable in bad weather. Otherwise, we were just soaking the Bedrug on tailgate and getting water in the camper. With the gutter, it’s like a covered porch in the rain.
Happy to answer any other questions. Hope this helps you.
