Which Sierra 3500HD does Edmunds recommend?
Edmunds' Expert Review
All heavy-duty trucks are built to handle rigorous towing and hauling needs, especially for professionals in construction and agriculture trades. But they also come in handy for intrepid trailer-travelers and those with a fondness for destroyer-class watercraft. The 2018 GMC Sierra 3500HD, however, adds another layer of comfort and luxury to all these utility tasks, and it does so with rugged exterior design and cabin comforts that you're more likely to find in high-end SUVs. If you want to bask in comfort while breaking a sweat, this is the truck.
Available with two powerful engines and in several cab configurations, the 3500HD can be tailored to fit your priorities, whether interior space, cargo room or maximum towing capacity. The optional diesel engine generates 910 pound-feet of torque — about a third of what a 60-ton Abrams tank engine produces — so there's not much beyond its capabilities before entering the realm of commercial freight hauling.
Ford and Ram also make robust, luxury-trimmed pickups for extreme towing duties, but you'll likely find the 2018 GMC Sierra 3500HD just as appealing.
2018 GMC Sierra 3500HD configurations
The 2018 GMC Sierra 3500HD heavy-duty pickup truck is available in four trim levels and three cab sizes: regular cab, double cab and crew cab. All are available with two- or four-wheel drive and in either single rear-wheel (SRW) or dual rear-wheel (DRW, or dually) configuration. All 3500 Sierras come with a long bed (8 feet 1 inch) except the crew cab, which in single rear-wheel form offers a choice of long bed or shorter standard bed (6 feet 6 inches).
For buyers interested in a basic heavy-duty truck, the base Sierra comes standard with a 6.0-liter V8 engine (360 horsepower and 380 pound-feet), a six-speed automatic transmission, 18-inch steel wheels, an automatic locking rear differential, xenon headlights, air conditioning, a choice of cloth or vinyl upholstery, a 40/20/40-split front bench with a fold-down center armrest, power door locks, manual crank windows, cruise control and a tilt-only steering wheel.
Also standard are a rearview camera, Bluetooth, a 7-inch touchscreen, a USB port, a four- (regular cab) or six-speaker sound system, and Apple CarPlay and Android Auto smartphone integration.
From the base Sierra on up, you also have your choice of engine. A turbocharged 6.6-liter diesel V8 (445 hp and 910 lb-ft) is available, also paired to a six-speed automatic transmission.
Many options are available for the base Sierra. Highlights include a remote locking tailgate, LED bed lighting, a 110-volt power outlet, satellite radio, and OnStar services with 4G LTE Wi-Fi.
For a slightly less bare-bones experience, the SLE offers an 8-inch touchscreen, 18-inch alloy wheels (single-rear-wheel models only), tinted rear windows, a remote-locking EZ-Lift tailgate, remote keyless entry, carpeted floor, a 60/40-split folding rear seat, full power accessories, a leather-wrapped steering wheel, a CD player, satellite and HD radio, and most of the base Sierra's options.
Further up the ladder is our recommendation, the SLT. Building on the SLE's equipment, the SLT adds foglights, power-folding mirrors, dual-zone automatic climate control, leather upholstery, power-adjustable and heated front seats, driver-seat memory settings, power-adjustable pedals, a tilt-and-telescoping steering wheel, an auto-dimming rearview mirror, remote ignition, and a 110-volt household-style power outlet.
For a luxurious take on your hard-working truck, go with the Denali. It adds a spray-in bedliner, a power-sliding rear window with defogger, front and rear parking sensors, a navigation system, wireless phone charging, a Bose audio system, an upgraded driver information display, upgraded interior trim, ventilated front seats and a heated steering wheel.
Many of the standard features on upper trims can be added at lower trim levels in grouped packages. Other optional highlights depend on trim level and include different axle ratios, a bed storage box, tonneau covers, trailering mirrors, a sunroof, a gooseneck/fifth-wheel trailering prep package, a rear-seat entertainment system, and a Driver Alert package, which includes front and rear parking sensors, lane departure warning, forward collision warning and a safety-alert driver's seat.
Only available on the SLT is the All Terrain HD package, which includes 18-inch wheels, the Z71 off-road suspension, skid plates, front-and-rear parking sensors and a heated steering wheel. A separate Suspension package (available on the SLE and the SLT) offers hill descent control, skid plates, specially tuned shock absorbers and unique styling treatments.

GMC Sierra 3500HD vs. the competition
2018 GMC Sierra 3500HD
2018 Ford F-350 Super Duty
GMC Sierra 3500HD vs. Ford F-350 Super Duty
Ford's burly heavy-duty truck features a recently fortified frame and aluminum bodywork for lighter weight. Also, its V8 diesel engine can twist even more earth than the Sierra's: 925 lb-ft versus the GMC's 910 lb-ft. That helps the F-350 reach a towing capacity several thousand pounds higher than the Sierra.
GMC Sierra 3500HD vs. Ram 3500
The Ram holds the current heavyweight title, with an optional diesel engine that makes 930 lb-ft of torque from just six cylinders. What can it do with all that power? For starters, it can tow a 30,000-pound fifth-wheel trailer. The Ram also offers far tamer V8 options for drivers who don't need to move mountains. But while the Ram is quite nice in its top trim level, the Sierra still wins for overall refinement.
GMC Sierra 3500HD vs. Chevrolet Silverado 3500HD
This is a fraternal battle that makes a winner out of either side. With both the Sierra and the Silverado sharing the same dimensions, capacities and mechanical elements, this decision comes down to features and creature comforts. Prefer your truck to be a truck and not worry about the ritual beatings of heavy-duty life? Get the Silverado. Need something with a little more panache while driving the partners out around the oil fields? Get the Sierra.
Sponsored cars related to the Sierra 3500HD
When you have work to do, sometimes a brawny pickup is the only way to get it done. Ideally, you'll get one from the 3500 class, sometimes called one-ton pickups (although this phrase refers to long-outdated payload capacities). These trucks are built for hard work, but the GMC Sierra 3500HD is also built for comfort and luxury, and that's what sets it apart from its rivals.
A close relative of the Chevrolet Silverado, the Sierra 3500HD is designed for buyers who want a truck with the features of a luxury car. Though GMC does make a work-truck version — the base model has vinyl floors and steel wheels — the Sierra 3500HD's cabin is a decidedly upscale place. High-quality materials abound, and the control layout uses large buttons and dials that are intuitively placed and easy to use. We like the intuitive infotainment system, and the cellphone storage pad in the center armrest is actually a wireless charger. The front seats are thickly padded, but we were surprised to see how hard they were; we actually think the rear seat of the crew cab is more comfortable.
This being a heavy-duty truck, there's more going on than a plush cabin. The base engine is a 6.0-liter gasoline-fueled V8 that develops 360 horsepower and 380 pound-feet. It's a good enough engine, but we do wish GMC would offer its HD trucks with the more powerful 6.2-liter V8 found in the Sierra 1500. We prefer the optional 6.6-liter Duramax turbodiesel, which was extensively reworked last year. The engine puts out 445 hp and 910 lb-ft of torque, with better refinement than its predecessor. Both engines come with a six-speed automatic transmission, though the diesel gets a beefier unit. The 3500HD is available in both single and dual rear-wheel models, both offered with rear- or four-wheel drive, the latter with a low-range transfer case.
As big as it is, the Sierra 3500HD is surprisingly pleasant to drive. The thin windshield pillars make for great visibility, and the steering has a nice heft, though the slow ratio means lots of wheel twirling when maneuvering.
GMC offers the Sierra 3500HD in a variety of models. The base model is, as mentioned, a bare-bones work truck, though those bones are decidedly more luxurious than most. The SLE and SLT models are aimed at buyers who want a more upscale truck. And for those who want it all, the top-of-the-line Sierra 3500HD Denali offers accoutrements usually found in luxury vehicles. Let Edmunds help you find the perfect 2018 GMC Sierra 3500HD for you.

Should I lease or buy a 2018 GMC Sierra 3500HD?
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.
