I have not done an awning but I did do the bedroom slide topper. Bought it from Tough Top, I believe. Yes it was, I just googled the name. I had a significantly younger and lighter Grand Son to help and we both watched the Tough Top video on YouTube.
Easy Peasy, took longer to get the tools ready and the ladders out than it did to replace the topper. DGS washed the top of the slide while the torn topper was off and I ground the points off two 16d framing nails to hold the tube in place.
Tough Top has videos specifically for their products. I'd do the awning in a heart beat and I'm 78 years old. With the DGS help of course.
