I have installed 11'+ window awnings. One on each side of the coach. For the same reason mentioned in the OP. I like the single awning providing shade and rain protection for two windows. With one awning there is no gap for the sun/rain to get through. After 7 years, I have had no problems of any kind with the awnings. I would make the same installation again.
