Never ever leave it out unattended. I learned that the first awning we had on a tt. We got it home and loaded that day. to the camp ground we went. Beautiful weather. Fell asleep. Three AM, wife and I wake at the same time and trailer is rocking. We realized the awning was still out. so at 3 AM Im out there in a thunder storm and pouring rain in my underwear, trying to get the thing rolled up. Fortunately, we only bent one of the arms! I was lifted off the ground several times try to get it rolled up. Last words from the dealership when we left with that day, Dont leave the awning out in storms , rain or unattended. I was lucky to learn with minimal damage. Oh and I got my finger pinched in the arms also when the wind would blow it around. I stress, never leave it unattended!
