With the introduction of the 2015 Chevrolet Silverado and GMC Sierra heavy duty pickup trucks came questions about why GM didn't improve their towing mirrors. After all, their fifth-wheel tow rating had been raised to just less than 23,000 pounds and their maximum conventional bumper ratings is class-leading at 19,600 pounds. But the towing package still offered the same manually operated oval mirrors.
Set to debut on the new High Country HD package, but eventually work their way into all Chevy pickups, the newly designed chrome towing mirrors incorporate side- and back-mounted clearance lights, projected cargo lamps and internal turn signals. They also fold into the door (for parking) with the touch of a button.
Additionally, since the new mirrors are newly electronically controlled, they are heated to limit and prevent ice buildup and fogging, and are tied into the preset memory feature that controls seating positions and mirror angles.
The new mirrors are still manually extendable (meaning you will have to be outside the truck and physically pull out each mirror to get the wider viewing angle), giving the driver better views of the rear trailer and cargo.
