This is what I ended up getting. I tried (3) Forest River dealers to get one (including the one that sold me the 25rrt). I tried Top Stitch (they used to make the screen walls for Forest River) but, they said they would get me a quote, never heard from them again.
This was a little wide for the 25rrt, I had to screw it into the side walls at the door frame instead of the door frame itself. It has worked great, heavy duty, easy to operate. My wife loves it!
