Dave's right in what he said.
Two years ago I seen first hand what happens when you leave your awning out.
We were camping for the 4th of July in Michigan's Thumb.
We had been tracking a storm on our computer and got ready for it and warned other people.
I was surprised at the people who did nothing after being told of the storm coming.
Many people had left the campground for the afternoon and left their awning's out.
The storm and wind came up very quickly.
That wind blew at about 60mph.
Later confirmed a Tornado had gone through, even though we didn't see one.
It rained hard and a lot of lighting.
Lost power a few times.
Trees down everywhere.
I helped some people try to get their awnings in, and it was a real job.
There were 2 of us on each arm to hold them down and wait for a little lull in the wind, then hurry up and roll them up.
These weren't electric.
The people who were gone and left their awnings out, the awnings whipped up over their trailers and bend all the arms.
It was really neat to see how the wind caught them and trashed them.
After the storm, we counted 12 awnings that were junk.
I don't know if any vents or skylights were broken, but I would bet some were.
There were a lot of unhappy people when they returned and saw the damage to their rigs.
So watch the weather forecast and put your awning up when you leave and if someone tells you a storm is coming, first put in the awning, then secure the rest of your things
