The 2015 Ram Heavy Duty pickups boast the highest tow ratings among one-ton pickups. Ram HDs offer more engine and transmission choices than competitors and a range of interiors from commercial-friendly to luxury.
The Ram 2500 (three-quarter ton) and Ram 3500 (one-ton) series were redesigned for the 2010 model year then were heavily revised for 2013, so changes for 2015 are minimal. Price changes are likewise minimal.
Maximum towing for the 2015 Ram 2500 is approximately 18,000 pounds and for the Ram 3500 it is 30,000 pounds; top payload approaches 4000 pounds for a Ram 2500 and 7320 pounds on Ram 3500. Like all full-size pickup trucks, the maximum tow rating and maximum load rating apply to different versions and not simultaneously. Ram’s payload numbers are fully competitive, the 3500’s towing ability is literally tons better than challengers and only one pickup, an F-450, tows more. (Most HD pickups pulling a trailer rated for anything near their maximum load capacity may require some sort of driver’s license beyond the norm or an endorsement.)
The 6.7-liter Cummins turbodiesel comes in three variants: 350-hp, 660 lb-ft with 6-speed manual; 370 hp, 800 lb-ft with 6-speed automatic; 385-hp, 865 lb-ft with 6-speed automatic on the MaxTow package.
Ram HD rides well and cruises quietly by heavy-duty pickup standards but you can’t compare the ride to a car, nor noise from six tires, lots of airflow and trailer hardware. We found the Ram 2500 with rear air suspension rode quite comfortably empty or towing, while four-door Ram 3500s towed comfortably into the 28,000-pound range. As with most full-size pickups, the four-door crew cabs tend to ride more nicely and isolate from vibration better due to their longer wheelbase and better body mounts.
Equipment levels vary from the basic Ram Tradesman’s rubber-vinyl coverings and crank windows to top trim levels with heated steering wheel, heated/ventilated front seats, driver memory system, configurable instrument cluster and text-to-voice infotainment systems. All cabs are roomy but the Ram MegaCab offers more cabin lounging space than any HD pickup.
Ram 2500 and Ram 3500 Heavy Duty models compete with Ford Super Duty, Chevrolet Silverado HD, and GMC Sierra HD pickups. Ram HD shares many interior elements and styling cues with Ram 1500 models, though they are not identical. Ram 3500 is also offered in a cab/chassis version, with straight frame rails and commercial intent just like the Ram 4500 and Ram 5500 series.
Ram HDs are a compelling choice for anyone in need of a heavy-duty pickup truck. Ram Heavy Duty models are an excellent choice for anyone pulling big travel trailers, multi-car race trailers, big boats or a stable of horses. They are a good choice for anyone who has work to do, be it hauling construction tools and materials or substituting for a medium-duty when a primary business rig is on downtime.
The 2015 Ram 2500 and 2015 Ram 3500 Heavy Duty pickups come in Tradesman, SLT, Outdoorsman, Power Wagon, Laramie, and Laramie Longhorn trim levels, plus regional SLT packages such as the Big Horn and Lone Star. Three cab configurations are available: Regular, Crew Cab, Mega Cab. Two bed lengths (6-foot, 4-inch and 8-foot) are offered, along with a choice of four wheelbases. Ram 3500 models are available with single or dual rear wheels (SRW or DRW). The Power Wagon is Crew Cab only; Ram HD regular cab is Tradesman or SLT trim only; Mega Cabs come only with the short bed.
Ram 2500 and Ram 3500 come standard with the 5.7-liter V8 and 6-speed automatic; no manual is offered for the V8s. A factory-built CNG (natural gas) unit is available on a few Ram 2500 Crew Cab long-box models. The 6.4-liter Hemi gas engine is available on most trims, including dual-rear wheel 3500. The Cummins 6.7-liter turbodiesel is available in three power levels with three corresponding transmissions. On most Ram HD models, part-time 4WD (manual or electric-shift) adds about $3,000.
Ram SLT adds power mirrors, remote keyless entry, power windows (including rear windows on four-doors), carpeting, cloth upholstery, electric-switched transfer case, chrome wheels, sliding rear window, in-dash tire-pressure display (2500 only) and the integrated trailer brake controller.

Ram Outdoorsman is a package for Ram 2500 and 3500 Crew cabs based on an SLT package with some additional extras.
