Hey. i was just reading on a forum about how you said you had the dealer swap out the smaller fold in mirrors with the big towing mirrors. Do you know if all dealers should be able to do this? My dad is in the market for a 2015 duramax and i told him to make sure he gets the bigger mirrors because he pulls an enclosed trailer for his business. He hasnt had much luck in finding a truck with everything that he wants, but figured if they could swap them out, that would be one less thing he had to have on the list.
Thanks
