Thule Omnistor - Manual and electric models

Does anyone have experience of using this awning? I appreciate it is more likely to be motorhomes since many caravans are not strong enough to have the unit attached. In particular, I am interested in its ability to withstand mildly windy conditions; I assume that if higher winds are anticipated it will have to be stored away. In addition, I am wondering if it can be temporarily rolled away wet. Would appreciate your experience and recommendations for using this unit.
