When I bought my first F350 back in 2011 I felt there were a number of little things that made Ford a better choice for me than what GM and Ram were offering. Things like power tow mirrors, tail gate ...
"Excellent chance I will be buying a 19 Ram HD, but will never ride with the mirrors up."
Let me know how that works out for you! On my 98 with 3rd gen flip up mirrors I ran with them down as the spot mirror worked the same when up or down. The 4th gen mirrors spot really only works well with the mirrors UP.
