I'll third the 12 mph mentioned by others. Also the never leave it out when you're away. My old RV had the manual kind that was a real pain to put up and take down and I did fudge those rules sometime. Of course, I also had the anti-flap clamps on it and a tie down system, so that would have helped. Had a friend on our church camp out at Fort Wilderness who left his out overnight and depended on the auto release feature to tip it for the rain. He woke up at 3:00 AM to the sound of the entire thing collapsing and pulling a large portion of the TT side with it. Not good. Ours was out but tipped and we didn't have an issue.
