I just had one put on for the dinning slide. 13 feet. It cost $466 installed. I went with basic white. Didn't need one over kitchen slide since the main awning covers that as well. I got a price from CW then went down the road to a company that only fixes campers and installs accessories. They do not sell campers. They did great work. I also found out they are a Forrest River authorized repair center and now handle all my warranty work. I found them by looking up domestic awning dealers. Definitely with putting an awning over the slide.
