My Daughter has decided to keep her stock mirrors on her Quigley and use the Milenco Grand Areo Towing Mirror's at the suggestion of the the good folks at Airstream , Thank you all for your quick response and suggestions . You can watch a You Tube demonstration of these mirror's if you Google Areo Grand Towing Mirrors , They look to be a very stable removable system . Thank you all again
