The rear area is capable of holding two adults in reasonable comfort. Leg and hip room are adequate and head room is extensive. This is one area where the Sierra shines when compared to the highly rated Toyota Tundra. The Tundra's rear area is cramped and the seatbacks are as straight as a redwood tree. Much thought was given to the dashboard and switchgear layout.
Climate controls are large and readable.
The stereo has large preset buttons up high on the dash and within easy reach of the driver. And GM retained the tuning knob which is vastly superior to pushing a switch. Storage room abounds. It's possible to put a six-pack of soft drinks in the center console. A full range of gauges are well laid out.
