Had that happen but didn't affect the coach driving. Just heard the noise and looked in my mirror and saw it flapping. Pulled over and was able to tie it down. But about a month before while driving across Oklahoma we heard what sounded like monkeys running on the roof. At least that's what Cindy said it sounded like. I climbed on top of the truck but couldn't see anything loose. Apparently it was the topper that was flapping.
