The heavy-duty truck crowd isn't a particularly tough one to satisfy. If you haul heavy objects, you're going to need some muscle and that's exactly what the 2015 Chevrolet Silverado 2500 and 3500 HD trucks offer. Like its corporate sibling - the 2015 GMC Sierra 2500 and 3500 HD - the Silverado HD is General Motors' response to Ford's F-Series Super Duty and Ram HD trucks. Both the Silverado 2500 and 3500 HD offer your choice of a 6.0-liter V8 gasoline engine and a 6.6-liter Duramax turbodiesel V8, the latter being legendary in its own right. The choices go on from different cab configurations to bed lengths to trim levels. While it's not the brawniest in class, the Silverado HD has plenty of brute strength to get the job done.
