I see you're in Central Oregon.....beautiful country! We'll be at Smith Rock SP next week to do some landscape painting with my group.
As to your awnings.....if you do a search (top right corner of this page) and type in "awning replacements".....you will find a number of sources for replacement awnings.
A forum member, "Lewster", is a dealer for ZipDee awnings and you could PM him for information also. He spends his summers in Hood River, OR.
Hope this helps.....and again Welcome!
