Engine math on the 2027 Ram 3500 is straightforward: 405 horsepower and 429 lb-ft from the 6.4L HEMI V8, or 430 horsepower and a best-in-class 1,075 lb-ft from the 6.7L Cummins High Output turbo diesel, each behind a TorqueFlite eight-speed automatic with 4x2 or 4x4.

Configured correctly, that becomes up to 37,020 pounds of towing and as much as 7,580 pounds of payload with the HEMI, or 6,460 pounds with the diesel. Dual rear wheels widen the stance for the heaviest fifth-wheel pin weights.

• Up to 37,020 pounds of towing when properly equipped
• Up to 7,580 pounds of payload with the HEMI V8
• 6,460 pounds of payload with the Cummins diesel
• 405-hp 6.4L HEMI V8 standard
• 430-hp, 1,075 lb-ft Cummins High Output available
• Single and dual rear wheel configurations

The 2027 Ram 3500 cockpit runs on screens that work as hard as the axles: a 12-inch Uconnect 5 touchscreen with an available class-largest 14.5-inch upgrade, a 12.3-inch digital cluster, and a class-exclusive available 10.25-inch passenger display.

Trailer-Tow Pages put hitch, brake, and lighting checks one tap deep, while an available 360-degree surround-view camera, a bed-mounted cargo camera, and an available digital rearview mirror with tow mode let one person line up a pin box without a spotter.

Running heavy on I-255 calls for depth in the driver aids, and the 2027 Ram 3500 supplies it: standard adaptive cruise control, plus available forward collision warning with automatic emergency braking and blind-spot monitoring that accounts for every foot of trailer behind dually fenders.

The integrated trailer brake controller is standard on every truck, available Trailer Reverse Steering Control takes the drama out of docking long trailers, and available factory fifth-wheel and gooseneck prep means the bed arrives ready for the hitch.

A one-ton that hauls weekly needs a cab worth sitting in, and the 2027 Ram 3500 covers the range: scrubbable Tradesman and Big Horn interiors, Laramie's leather-trimmed buckets, and the Limited Longhorn and Limited with filigree-stitched hides, genuine wood, and metal detailing.

Up to six ride on the available front bench, the class-exclusive Mega Cab adds reclining rear seats, and available heated and ventilated front chairs handle both ends of a Midwest year. An available 17-speaker Harman Kardon system makes the miles between stops easier.

• Seating for up to six with the available front bench
