We love our slide out awnings, I installed them at a little higher angle than the factory does so we have not water pooling on our awnings.
Have heard very little flapping in the wind but since many times we stay in a lot of CGs with trees, they are great keeping the leaves, twigs and debris off the top of our slides.
