Which 2500 does Edmunds recommend?
Edmunds' Expert Review
As versatile as they are, light-duty trucks are not one-size-fits-all vehicles, especially if you have serious towing and hauling needs. For that, you'll need to step up to a heavy-duty pickup such as the 2018 Ram 2500. To put it into numbers, the Ram 1500 carries a max tow and payload rating of 10,620 pounds and 1,880 pounds, respectively. The Ram 2500 comes close to doubling those figures by towing up to 17,980 pounds and carrying 3,890 pounds in the bed.
The Ram 2500 is unique in the heavy-duty truck segment because of its coil-spring rear suspension that gives it a more comfortable ride than its competitors. Such a configuration also allows for an air suspension, just like the one available for the Ram 1500. Besides improved ride comfort, the air suspension levels the bed when towing and hauling to keep the headlights pointed straight ahead.
The 2018 Ram 2500 offers something for everyone, whether you're looking for a basic work truck, a luxury equipment hauler or a trail-conquering pickup. It's an excellent all-rounder that surpasses many rivals.
Notably, we picked the 2018 Ram 2500 (including the Ram 2500 Diesel) as one of Edmunds' Best Trucks for this year.
2018 Ram 2500 configurations
Like many heavy-duty pickups, the 2018 Ram 2500 is available in multiple configurations. There are three cab styles, two bed lengths, three engines, two transmissions and seven trim levels: Tradesman, SLT, Big Horn/Lone Star, Laramie, Laramie Longhorn, Limited and Power Wagon. At one end of the spectrum is the Tradesman, a minimal-frills workhorse. At the other, the Limited, widens the boundaries of big-truck luxury. The Power Wagon stands alone as the off-road-ready variant.
Cab styles include a two-door regular cab, a four-door crew cab, and a four-door jumbo crew cab called the Mega Cab. The regular cab comes with a long bed (8 feet) only, while the crew cab has either the long bed or the short bed (6 feet 4 inches). The Mega Cab rides on the same wheelbase as the long-bed crew cab but combines an even bigger cabin with the short bed.
Most 2500s come with a 5.7-liter V8 gasoline engine (383 horsepower, 400 pound-feet of torque) paired with a six-speed automatic transmission. A modified version of this engine runs on compressed natural gas (CNG) and produces identical power figures to the gasoline version. The CNG option is only available on regular and crew-cab models with the 8-foot bed.
There are two optional engines: a 6.4-liter V8 (410 hp, 429 lb-ft of torque) paired to a six-speed automatic transmission and a turbocharged 6.7-liter diesel six-cylinder. The latter makes 350 hp and 660 lb-ft when matched to a six-speed manual transmission. When paired with a reinforced six-speed automatic, those numbers are 370 hp and 800 lb-ft of torque.
The Tradesman and SLT trims are available with all three cabs, while the Big Horn/Lone Star, Laramie, Laramie Longhorn and Limited versions can only be ordered with a crew cab or a Mega Cab. The off-road Power Wagon variant (crew cab, short bed only) can be ordered in Tradesman and standard forms.
The 2500 is available with either rear-wheel drive or part-time four-wheel drive, except the Power Wagon, which is available in 4WD form only.
The Tradesman is the most basic trim. Standard feature highlights include 17-inch steel wheels, a locking tailgate, air conditioning, a 40/20/40-split front bench, a tilt-only steering wheel, a driver information display, vinyl upholstery, an auto-dimming rearview mirror with an incorporated rearview camera display, and a six-speaker stereo with a USB port.
Power windows and locks, including the locking tailgate, are standard on crew-cab models, as are power-adjustable and heated mirrors. Regular-cab models have manual controls and non-heated mirrors by default.
The SLT adds chrome exterior trim, 18-inch steel wheels, an integrated trailer brake controller, power heated mirrors, a power-sliding rear window (manual on regular cabs), remote locking and unlocking, an overhead console, cloth upholstery, carpeted floors, full power accessories for all body styles, Bluetooth, satellite radio, and a 5-inch touchscreen interface that displays the rearview camera image.
The Big Horn (Lone Star for shoppers in Texas) adds 18-inch alloy wheels, a limited-slip rear differential, chrome grille slats, foglights, remote ignition, a 115-volt power outlet, a power-adjustable driver's seat, premium cloth upholstery and an extra charge-only USB port.
The Laramie builds off the Big Horn /Lone Star and adds a standard 6.4-liter V8, more chrome trim (including the bumpers), projector headlights, LED taillights, power-folding and auto-dimming mirrors, front and rear parking sensors, dual-zone automatic climate control, leather upholstery, driver-seat memory settings, a power-adjustable front passenger seat, heated and ventilated front seats, a heated steering wheel, an upgraded driver information display, a 10-speaker surround-sound audio system, HD radio, a 4G LTE Wi-Fi hotspot, and an 8.4-inch touchscreen with Apple CarPlay and Android Auto. The limited-slip differential is dropped as standard equipment but is available as an option.
The Laramie Longhorn adds to the Laramie's substantial features list by including a chrome mesh grille, accent-colored bumpers, running boards, a spray-in bedliner, LED bed lights, remote ignition, a full center console, upgraded floor mats, upgraded leather upholstery, wood interior and steering wheel trim, power-adjustable pedals with memory settings, front bucket seats, heated rear seats and a navigation system.
The Limited trim adds monotone paint, color-keyed bumpers, 20-inch wheels, additional chrome exterior trim, automatic high beams, automatic wipers, the RamBox cargo management system (includes bedside storage compartments, an adjustable bed divider and tie-downs), keyless entry and ignition, and special black leather upholstery.
Finally, there's the off-road-themed Power Wagon, which is available only in crew-cab 4WD with the short bed and the 6.4-liter V8. It has some slightly different exterior and interior styling changes, but it's the extensive mechanical upgrades that make a Power Wagon. They include unique 17-inch wheels shod with aggressive all-terrain tires, Bilstein off-road shock absorbers, tow hooks, skid plates, a manual transfer case, electronically locking front and rear differentials with a 4.10 axle ratio, hill descent control, an integrated front winch, and a front anti-roll bar than can be disconnected electronically to improve wheel articulation off-road.
Interestingly, the Power Wagon isn't just a trim level. It's also an option package you can add to a crew-cab Tradesman 4x4 with a 6.4-liter Hemi engine. Here you'll get all of the Power Wagon mechanical bits, including the fender flares, but without any other bodywork styling cues or graphics. It's a stealthy working man's Power Wagon at a lower price.
Those who aren't looking for the extreme capability of the Power Wagon can select the 4x4 Off-Road package that is available on 2500 crew-cab and Mega Cab 4x4 models. This package is available with any engine and includes hill descent control, tow hooks, a transfer case skid plate, upgraded shocks, a limited-slip differential, and all-terrain tires.
Many upper trim features are available on lower trim levels as part of packages or as stand-alone options. Other option highlights include a load-leveling air suspension, tow mirrors, a cargo-view camera, fifth-wheel trailer preparation, off-road tires, a CD player and a sunroof.
Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our full test of a Ram 2500 Laramie Longhorn Crew Cab (turbo 6.7L inline-6 diesel | 6-speed automatic | 4WD).
NOTE: Since this test was conducted, the current Ram 2500 has received some revisions, including a revised 8.4-inch touchscreen system for 2018. Our findings remain applicable to this year's Ram 2500.

2018 Ram 2500 Mega Cab for Sale
Half-ton pickups (those with 150 or 1500 in the model name) may seem big and burly, but there are some jobs they just can't do. If you have serious loads to haul, you'll need to step up to a heavy-duty pickup. We consider the 2018 Ram 2500 to be a top pick because it bundles tremendous towing and hauling abilities with best-in-class ride comfort.
What sets the Ram 2500 apart from the competition is its coil-spring rear suspension. It stands in stark contrast to the leaf springs that have been used in trucks since Henry Ford first put a pickup bed on a Model T. Coils provide a more comfortable ride — though such things must be considered in their context; any truck built to haul this much weight is going to ride firmly. They also maintain better control of the rear axle, which means that bumps and ripples don't send the rear end skittering around as much as a leaf-spring-equipped truck. The Ram's steering is heavy yet accurate, and it tracks through the corners very nicely considering its bulk. A roomy well-finished cabin with easy-to-use controls rounds out this likable truck.
The base engine in the Ram 2500 is a 5.7-liter gasoline-fueled V8 (also available in a natural-gas-fueled version) that delivers 383 horsepower and 400 pound-feet. An optional 6.4-liter V8 puts out 410 hp and 429 lb-ft, and both engines come with a six-speed automatic transmission. But the Ram 2500 is arguably most famous for its 6.7-liter six-cylinder turbodiesel built by big-rig diesel manufacturer Cummins. Ram is also the only manufacturer offering a heavy-duty pickup with a manual transmission; it comes paired to a 350-hp, 660 lb-ft version of the Cummins engine. But if you want to unleash the diesel's full potential, you'll need to opt for an automatic. So equipped, output rises to 370 hp and 800 lb-ft of torque. Because of the truck's weight capacity, Ram is not required to provide EPA fuel economy estimates.
Speed is not the diesel Ram's mission in life, but we still clocked it to 60 mph in a respectable 8.7 seconds. This is a workhorse, and work it does: Properly equipped, the Ram 2500 can haul up to 3,890 pounds in the bed and tow up to 17,980 pounds.
The Ram 2500 is offered with three cab styles (regular, extended and crew); two bed lengths; and seven trim levels: Tradesman, SLT, Big Horn (sold in Texas as the Lone Star), Laramie, Laramie Longhorn, Limited and Power Wagon. The Tradesman is a stripped-down work truck designed to deliver lots of ability at a low price point, while the Limited has bells and whistles we'd expect from a luxury car. The Power Wagon is an off-road-themed version with a manual transfer case and other off-road-specific features, many of which are available on other models as part of the Off-Road package. Whichever suits you best, Edmunds can help find the perfect 2018 Ram 2500 for you.

Should I lease or buy a 2018 Ram 2500?
Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
