Glad you had a good time...as others have said..the antenna crank is bound to fall apart at some point in time. I finally just replaced mine last year after getting parts while at the Rally last year. This year, I had the bedroom door ripped from its hinges(yes it was strapped down) due to the rough roads in Minnesota. After taking the door off, straightening the hinge, resetting the screws, and re-installing, it survived the 700+ mile trip back home in one piece. Let us know what you find out about the tank wash...
