What You Will Like

While the standard Silverado represents a pretty good value for those wanting a work truck that's easy to live with, the Silverado HD offers far more utility than the standard truck with the ability to tow bigger loads and generally fit more in their beds. However, like most modern pickup trucks, the Silverado HD models offer a fair amount of livability considering how capable they are as work vehicles. Both the 2500HD and the 3500HD models can be optioned up with a ton of interior convenience features as well as the latest safety equipment. In addition, Chevrolet have gone out of the way to add technology where these vehicles will need it: Towing. The new Silverado HD offers up to fifteen unique camera views including a "transparent trailer" mode that offers to revolutionize rear visibility while towing.
