It’s really quite easy. I’ve done it. Put your awning out in the rain and don’t have one end of it a lot lower than the other end. When the awning fills up with water, the awning supports will snap and the pieces attached to the spring mechanism will spin around and thrash the aluminum on the side of your trailer. It sounds like your tailer has been hit by lightning and it shakes the heck out everything. Quite exhilarating, expensive and is best experienced on the second day of your vacation. I know.
