When you’re hauling in Ohio, big trailers call for big power — and that starts with the right truck. The Ram 2500 diesel delivers impressive torque and easily accommodates both a fifth wheel and a work trailer. So whether you’re heading to Put-in-Bay with the family camper or hauling equipment across the Buckeye State, you can have confidence that it’ll handle heavy lifting effortlessly. We hope this guide, compiled by us at Bob Caldwell Chrysler Dodge Jeep Ram (CDJR), helps you better understand the towing capabilities of this impressive diesel.

Why the Ram 2500 Diesel Dominates Ohio’s Heavy-Duty Towing Market

According to Ram’s data, 70% of 2500 buyers choose diesel. This choice makes sense since 90% of these owners are using them as work trucks — hauling trailers and carrying heavy loads. Ram cleverly engineered the 2500’s strong torque to kick in early and stay consistent, which is crucial for Ohio’s rolling hills when you’re pulling maximum weight. The latest model showed several enhancements, including a 0-to-60 mph sprint time of 6.9 seconds, an improvement from the previous model’s 8 seconds. This may not sound like much until you’re merging onto I-270 during rush hour towing a heavy load.

Understanding Ram 2500 Diesel Towing Fundamentals

The Ram 2500 diesel’s towing capacity of 20,000 pounds, when properly equipped, demonstrates how its high torque rating of 1,075 lb-ft at a low rpm makes it the perfect workhorse. Its newly available 430-horsepower, high-output 6.7-liter Cummins turbo diesel engine is paired with the TorqueFlight eight-speed transmission. This configuration is further enhanced by a fuel pump that injects diesel into the cylinders at 30,000 psi, which is three times what most gas engines manage.

Ram diesel trucks feature a 3.42 rear axle ratio and a low first gear that makes moving heavy loads easy, especially with the Ram 2500’s payload capacity of up to 4,000 pounds. Eight gears ensure the engine stays in its optimal range, whether you’re climbing through Hocking Hills or cruising flat stretches of I-80. Enhanced airflow management and the high-pressure fuel system keep power consistent even during summer heat.

The variable-geometry turbo automatically adjusts based on load and altitude, while advanced glow plugs improve start-up times, even when it’s below zero. You get low vibration and minimal noise with the smarter valve train gears.

Fifth-Wheel Towing Excellence With Ram 2500

Fifth-wheel rigs push the limits of any truck, and the Ram 2500 diesel passes with room to spare. It features multiple camera angles, adjustable fish-eye mirrors, digital rearview setups, and blind-spot monitoring that accurately measures your trailer’s length, taking the guesswork out of tight spots. The diesel’s exhaust brake works in conjunction with Tow/Haul mode for smooth, controlled descents.

If you found backing into campground spots challenging, you won’t anymore. The trailer steering control allows you to guide the trailer by turning a knob while the truck steers itself. The REESE M5 fifth wheel hitch has a 32,000-pound capacity that uses Talon Jaw Technology to securely grip kingpins. It’s designed to be installed without drilling holes in your truck bed.

Typically, fifth wheels range in height from 11 feet, 6 inches to 13 feet, 5 inches, with 13 feet, 6 inches being the legal maximum in a majority of states. Weight distribution remains balanced even when crosswinds hit on I-90, allowing you to feel secure and confident instead of gripping the wheel in anxiety.

Ohio-Specific Towing Considerations

Before hitting the road, make sure you’re familiar with Ohio’s laws and standards for every type of trailer on the road. The maximum trailer height is 13.6 feet; the maximum width is 8.6 feet; and the maximum length is 65 feet. The gross vehicle weight must not exceed 80,000 pounds. All trailers built after January 1942 and weighing over 2,000 pounds when empty must have their own brakes. Ram’s integrated brake controller and monitoring systems keep you legal without stress.
