Used 2020 Ram 2500 Mega Cab

Standard power comes from a 6.4-liter V8 (410 hp, 429 lb-ft of torque) paired with an eight-speed automatic transmission. Aside from the Power Wagon, every Ram 2500 also offers an available turbocharged 6.7-liter diesel six-cylinder engine (370 hp, 850 lb-ft) paired with a six-speed automatic. Four-wheel drive is optional on all but the Power Wagon, which comes with standard four-wheel drive.

The Tradesman is the most basic trim. Standard features include 17-inch steel wheels, air conditioning, a front bench with vinyl upholstery, a tilt-only steering wheel, Bluetooth, a USB port and a 5-inch touchscreen interface. Power windows and locks are standard on crew-cab models, as are power-adjustable heated mirrors.

The Big Horn (Lone Star for shoppers in Texas) adds chrome exterior trim, 18-inch steel wheels, an integrated trailer brake controller, remote locking and unlocking, a power-sliding rear window, remote ignition, cloth upholstery, carpeted floors, and an extra charge-only USB port.

The Laramie, Longhorn and Limited build off the Big Horn/Lone Star, adding more features, more chrome and more premium interior touches. Highlights, depending on the trim, include LED lighting, a 115-volt power outlet, power-folding auto-dimming mirrors, parking sensors, dual-zone automatic climate control, a power-adjustable driver's seat, leather upholstery, heated and ventilated front seats, a larger infotainment screen, Apple CarPlay and Android Auto smartphone integration, and the RamBox cargo management system (includes bedside storage compartments, an adjustable bed divider and tie-downs).

Many features are available on lower trim levels as part of packages or as stand-alone options. Other key options include a load-leveling air suspension, tow mirrors, a cargo-view camera, adaptive cruise control, blind-spot monitoring with rear cross-traffic alert, forward collision warning, a 360-degree surround-view parking camera, fifth-wheel trailer preparation and a sunroof.

Finally, there's the off-road-themed Power Wagon. It adds some visual flair and brings upgrades including all-terrain tires, off-road shock absorbers, tow hooks, skid plates, a manual transfer case, electronically locking differentials with a 4.10 axle ratio, hill descent control, an integrated front winch, and an electronic disconnect for the front stabilizer bar. The Power Wagon option package can also be added to a crew-cab Tradesman V8 4WD. You get all of the Power Wagon mechanical bits but none of the bodywork styling cues or graphics.
