RV trailer retracted awning weather protection

Only enclosed fabric awnings I've seen have been attached to high end DP's and Prevost conversions. So I guess they're out there if you have the $$$$. Haven't unfurled the Dometic awning on our new TT yet. It's doing a nice job of looking like hell on its own..................Gotta wash it and the rest of the trailer this weekend when "fall" finally finds Florida.
