The 2020 Dodge Ram 3500 Dually represents the pinnacle of full-size pickup capability, merging robust diesel power with serious towing capacity in a package built for serious work. This specific model year, positioned as the final year of the fourth-generation Ram design, offered a level of confidence-inspiring performance that few vehicles on the road can match. It is a machine engineered to haul massive trailers and heavy equipment while maintaining a demeanor suitable for daily driving, making it a unique tool for professionals and enthusiasts alike.
The Heart of the Beast: Duramax Power and Capability
The defining feature of the 2020 Ram 3500 Dually is its available powertrain, a legendary Cummins 6.7-liter inline-six turbodiesel engine. Producing a robust 400 horsepower and an astonishing 1,000 lb-ft of torque, this powerplant transforms the truck into a towing titan. This immense torque figure is available at a relatively low RPM, ensuring smooth, confident pulls from a standstill without straining the engine. The diesel’s character, a deep, purposeful growl rather than a sharp buzz, provides a reassuring soundtrack to any heavy-duty task.
Mated to this powerhouse is a choice of transmissions, primarily the heavy-duty TorFlite six-speed automatic or the more recent eight-speed automatic. Both are built to handle the immense stresses generated by the 3500 Dually’s capabilities. The four-wheel-drive system, paired with a locking rear differential, ensures that this massive truck maintains traction and composure in challenging conditions, whether navigating a muddy job site or traversing uneven terrain under a heavy load.
Engineering the Dually: Chassis and Suspension Design
The "Dually" designation is more than a badge; it is a fundamental engineering reality that defines the truck's capabilities. The 2020 Ram 3500 Dually features an extra set of rear wheels and tires, mounted on a dual rear wheel (DRW) axle. This configuration dramatically increases the tire contact patch with the ground, distributing weight and providing exceptional stability and traction. The visual impact is immediate and commanding, giving the truck a presence that is impossible to ignore.
To support this unique layout and the truck's immense duty cycle, the chassis is built with a robust, heavy-gauge steel frame. The front suspension utilizes a heavy-duty coil spring design, while the rear axle is a robust, fully boxed C-notch design specifically engineered to handle the stresses of the dual wheels and massive payloads. This results in a truck that feels planted and stable, even when fully loaded and navigating tight corners or highway winds.
Payload and Towing: Exceeding Expectations
Performance figures are impressive, but the true measure of the 2020 Ram 3500 Dually is its real-world capability. This truck consistently ranks at the top of its class for maximum towing capacity, with figures reaching up to 37,000 pounds when properly equipped. This allows it to tow massive fifth-wheel trailers, heavy equipment, or large boats with ease, making it a favorite among contractors, landscapers, and serious recreational users.
The payload capacity is equally staggering, with maximum figures exceeding 7,000 pounds. This means the bed can carry substantial amounts of materials, tools, and gear without issue. The available air suspension system is a key component in managing this load, offering adjustable ride height and level control to ensure the truck remains stable and functional regardless of the weight in the bed or the trailer being towed.
Interior and Technology: Comfort Meets Utility
Inside the 2020 Ram 3500 Dually, the focus shifts from brute force to refined comfort and technology. The cabin is surprisingly spacious, even with the dual rear wheels, offering ample headroom and legroom for all occupants. Premium materials, available leather-trimmed seating, and advanced climate control contribute to a luxurious environment that is far removed from the utilitarian cabs of work trucks past.
