The more heavy duty pickup from Chevy’s Silverado line is the HD which is offered in 2500 and 3500 series. For the 2013 model year, it can be equipped with a compressed natural gas powertrain. The Silverado HD is available in less configurations than the smaller Silverado 1500, but it’s a trade off for higher capacity maximum towing and payload. Buyers can opt for either a standard gasoline engine of a turbo-diesel powerplant.
