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 ...
I am sure the ford mirrors work well. But iMHO that is not a reason to buy a truck. Funny part is that seems to be the number one reason given for buying a Ford.
I REALLY like my folding mirrors. Actually I never fold them down. I do use the fold away option every time I park my truck.
