RVing for over 40 years in trailers, Class C, Class B, Class A's. Never left an awning out when we left the site. Fulltimed for 15 years. Never lost an awning. We had one microburst hit it on a very calm day at a campground. It actually caused the fabric to move forward on the tube enough that when we retracted it, it would not completely close. This was on a 40' Phaeton. So we visited our favorite service center the next morning on our way out of town. Two guys and 20 minutes they had it slide back down into place. We couldn't have done it, but they knew what they were doing.
I have our small B+ now and the awning was old and deteriorated. I had the fabric replaced and learned how to open/close this manual awning. I still never leave it out if I leave the site.
