We have the 'carefree' on ours, which is set so the rear (toward the rear of the coach) of the awning is noticeably lower than the front, I'm guessing to drain water off. Since it has never been out while it was raining, can't say how well it may or may not work, but, not sure I really want to test it either. As far as wind sensor, it has sort of an imitation wind sensor, which is, if the awning if buffeted up and down it will retract. That I have tested, by raising and lower the outside edge of the awning with a broom. Shake it up and down, it does retract. How well that works in the real world of wind, don't know.
