I was just reading RV-Open Road Forum (do read other forums sometimes)and there was one on ttt mirrors , whatever they are. Any way all the replys seemed to be from chevy/GMC owners. I was wondering if the Ford F350 telescoping factory mirrors are adequate for towing a fiver. I know we have several Ford truck owners in this forum. I am sure MR.SREIGLE can help me on this one. Thanks.
