I rented my MH to a friend once and only once. He left the awning out while he was away for a couple of days. What a mess. So YES. do bring the awning in when leaving and when going to bed. It is no fun being outside in pouring rain at 3 am in your pajamas.
I also saw an airstream whose awning was out and we got a sudden windstorm. No warning. The wind ballooned the awning as though it was the main sail on a clipper. The awning did not get ripped off. Instead it flipped the airstream on it's side.
The best advice for RVers....Always think of Murphy's Law.:B
