The HD Silverado and its twin, the GMC Sierra HD, are designed for heavy towing and hauling.
The 6.0-liter V8 and 6.6-liter turbodiesel are both mated to a six-speed automatic.
The latter works well and employs a heavy-duty Allison-made transmission.
A natural-gas version of the 6.0-liter V8 is also available.
The LTZ trim has a luxurious cabin.
