They are fine in a wind. In fact, they help stabilize the awning in moderate breezes. You stake down the bottom so it acts as a hold down device.

You want the style that has a permanent piece on the awning rail and the main shade zips on or off. The permanent piece rolls up with the awning with no issues. Be sure to get enough drop in the permanent piece (I think they come in 1', 2', and 3' depths) so that the zipper is reachable (without a ladder or step stool). The longer the drop, the more the removable piece is allowed to be staked down further away from the RV and provides a bit more room.
