Yet, these buyers all appear to have several things in common. They want their trucks to look bold and aggressive but the “absolute, number one priority is towing,” said Jaclyn McQuaid, the chief engineer for both of GM’s HD models. The 2020 Chevrolet Silverado 3500 HD version, equipped with a diesel V-8, has a maximum towing capacity of 35,500 pounds, a 52 percent increase from the outgoing model.
At its own preview of the Sierra Denali HD last month, GMC unveiled the truck at the San Diego waterfront where the dually, outfitted with a diesel engine, pulled a yacht and life boat weighing 225,000 pounds. Officials said they made no modifications to the truck other than to the tow hitch itself.
Fiat Chrysler’s new HD line adds an updated Cummins diesel engine that is the first ever to top 1,000 pound-feet of torque. It only narrowly falls short of the GM HD models when it comes to a towing capacity of 35,100 pounds. But it also can haul 6,570 pounds of cargo in its bed.
