2021 Ram HD Ram3500 Towing and Payload Capacity Fuel Economy and Real-World MPG

Towing and Payload Capacity

With the Cummins HO and its 1000 lb-ft of torque, a Ram 3500 has a towing capacity of 37,100 pounds and a maximum payload of 7680 pounds. When equipped with that engine, the more popular 2500 4x4 Crew Cab model offers a max payload of 2380 pounds and max trailer-weight rating of 19,010 pounds. Those are strong numbers for the class. With the 370-hp version of the Cummins, the 2500 4x4 Crew Cab can haul 3240 pounds and pull 16,870. With the standard V-8, the truck can also handle 3240 pounds, and tow 14,370, which is more than enough for most jobs and weekend expeditions.

Fuel Economy and Real-World MPG

Fuel economy is not estimated by the EPA on commercial vehicles such as the Ram 2500 and 3500 with a Gross Vehicle Weight Rating (GVWR) of more than 8500 pounds. While we've only tested one of these gargantuan Rams—a 3500 with the high-output Cummins, four-wheel drive, mega cab, and dual-rear-wheel axle—it earned 16 mpg on our 75-mph real-world fuel-economy route, which is part of our extensive testing regiment.
