A brand new truck with an old four-speed automatic transmission is disappointing, as is the dual gloveboxglove box on the Pure Pickup interior trims; there’s not very much space, and it’s a little hard to use. Negatives also include the lack of a real effective tailgate-assist mechanism, and the absence of a composite-lined bed. Perhaps as a dealer accessory? Yes, there is an optional rail system, but without a protective sleeve inside the bed it likely won’t take long for your Sierra to show its age. For some truck buyers, however, that’s a good thing, for it shows a truck in use, and we can’t argue with that logic.
