My last coach had a manual awning, my current coach has an automatic electric awning. My experiences:
It's so easy to extend and retract the electric awning!
The wind sensor (thermistor) does work - after I properly set the DIP switches.
The electric awning is either in, partially out, or out. But, I can't control the angle.
My awning does automatically shed water during a rain.
With my remote control, I can extend or retract the awning without going outside in the dark, or during a high wind, or....
I NEVER leave my awning out at night or when we are not at the motorhome.
With the electric awning, I don't have to tug on straps, set braces, or tighten knobs - just press a switch.
All things considered, I think the lazy side of me prefers the electric automatic awning.
