Hello, I have a hymer 544 and would like to fit a full length awning,Im not sure how i go about measuring the size needed or who to order from. Any help or advice please. Lee
NR Awnings, Dorema, and I imagine other websites, offer the same advice as in rustyfrog's link, i.e. awning size is based on the length of the awning channel plus the distance to the ground at each end.
This site's Company Directory lists quite a few suppliers.
