The TT we sold this spring had a manual awning. When we deployed it at the beginning of a trip it got tilted for drainage, the de-flappers went on and it was firmly staked with ratchet straps. It stayed up rain or shine in all but the strongest winds.
Our new-to-us Rockwood 2701SS has a power awning and I have mixed feelings about it. Up until now we've put it away in a stiff breeze, every time we leave the campsite and when we go to sleep. But I miss having a big sheltered area for our stuff, especially overnight.
Next time we go out I am going to tilt it for run-off, stake it down with cam straps and sit under it until the wind blows so I can see how it behaves.
