I now have an awning on my slide, but I want to install a slide topper to keep debris and water off the top of the slide. I also want to keep the sun off the seals. I ordered a Dometic Elite slide topper and am wondering if anyone has ever installed one of these themselves? I may have to remove the existing awning altogether, but I think the slide topper will be of more value than the awning. Any comments; good,bad or indifferent?
