Put in a reservation for a refreshed 2022 AT4 1500 with the 3.0 Duramax w max tow back in Jan. Dealer contacted me today, he said they received production allocation and were trying to enter my specs into the order system but it keeps rejecting the truck because of the towing mirrors. Systems shows "DQS NO LONGER AVAILABLE". He told me they have removed trailer mirrors as an option entirely from all refreshed 2022s. Can this be so, or is my guy misinformed?
