When it comes to hauling the big loads, there are few rivals to the heavy-duty full-size pickup. With its reinforced chassis and choice of high-powered engines, the heavy-duty pickup has the highest towing capacity and payload of any pickup on the road. This is also a market made up solely of domestic products.

Most heavy-duty pickups are used for commercial purposes, or to tow trailers and recreational vehicles. Key one-ton players in this rough-and-tumble market include the Chevrolet Silverado 3500/GMC Sierra 3500, F-350 Super Duty and the Dodge Ram 3500.

Heavy-Duty Pickup News
With their first complete redesign in over ten years, the all-new heavy-duty Chevrolet Silverado 2500HD and Chevrolet Silverado 3500 and GMC Sierra 2500HD and 3500 went on sale in 2001, giving Ford and Dodge formidable competition.

However, Dodge answered the challenge with the release of its all-new heavy-duty pickups for the 2003 model year. The Ram 2500 and Ram 3500, unveiled at the Chicago Auto Show in February, 2002, sport the same aggressive look as the Ram 1500. The new trucks are available with a new 5.7-liter HEMI Magnum V8 as well as a powerful 5.9-liter diesel.

Speaking of diesel power, Ford now offers an all-new 32-valve 6.0-liter V-8 Power Stroke diesel engine for its SuperDuty lineup. The new engine not only boasts 325 horsepower at 3300 rpm and 560 lb-ft of torque at 2000 rpm, but also features better fuel economy and lower emissions than the 7.3-liter engine it replaces.

The General Motors offerings are also available with impressive diesel power. The optional 6.6-liter diesel provides a whopping 590 lb-ft of torque at just 1600 rpm.
