We have a 2007 Komfort 26BHS and I had to replace my awning material two years ago. I went with something very similar to the original vinyl that came with the trailer. On our Komfort trailer is a 19 ft , Awning_Brand: A&E Systems, Awning_Model: Dometic Sunchaser. I ordered it from
http://www.shadepro.net/product/Replacement_Patio_Canopies/repfab_pv_standard.html at a price of $169 with free ship.
I also just watch a few youtube videos on safe replacement of the awning material and had my wife help me when needed.
