Impressive towing and hauling capabilities; huge power and torque from any engine; new interior is a major improvement
Manual transmission would be nice; pricing a little steep; no self-leveling suspension like RAM HD
The GMC Sierra 3500HD is fully redesigned for the 2015 model year. While it keeps last year's engines, the latest Sierra boasts new styling, a revised interior, new equipment and a new double-cab model that replaces last year's extended cab.
Because there are so many versions of the Sierra 3500HD, recommending the right one is a difficult task. In the end, we like the pickup, and we think you'll need to carefully consider the model lineup to decide which one is the best for you. If you're looking for a family hauler, it'll be the crew cab. Want to tow a trailer? Go for the turbodiesel. No matter what your desire, truck shoppers will find something for just about everyone in the Sierra 3500HD. Find a GMC Sierra 3500HD for sale
The Sierra 3500HD comes in a wide variety of trim levels, body styles and configurations. There are regular cabs and crew cabs, and for the 2015 model year, there's now an extended cab model with four full doors. There are regular beds and long beds, gasoline and diesel engines, and 2- and 4-wheel drive. Drivers can also choose between two rear wheels or four (a dually), depending on their desired payload capacity.
When it comes to trim levels, the Sierra 3500HD offers four: a base-level Sierra model, mid-level SLE and SLT trims, and an upscale luxury-oriented Sierra Denali.
Choose the Sierra ($34,200) and you'll get only the basics, as this trim level is primarily designed for use on gritty jobsites. Standard features include an AM/FM stereo with an auxiliary port (but no CD player), air conditioning, vinyl seating and little else. In fact, these Sierra 3500HD models don't even include features such as keyless entry or power mirrors.
Next up is the SLE ($37,800), which adds many missing creature comforts as standard equipment. There are heated mirrors, for instance, and remote keyless entry. There's GM's OnStar telematics system, which can provide directions and other assistance. And there's a standard backup camera, which is helpful in a truck this large.
Slotting above the SLE is the SLT ($46,200), which offers all the luxury that most shoppers will ever need. There's leather upholstery, dual-zone automatic climate control, chrome door handles, LED lighting and heated front seats. SLT models also offer available front and rear park assist.
Topping the Sierra HD's range is the Denali ($51,700), which adds a long list of high-end equipment. Features include a heated steering wheel, cooled front seats, additional chrome accents, a vastly improved interior with contrasting stitching and aluminum trim, and a navigation system.
In addition to the Sierra 3500HD's standard features, the truck also offers quite a few options. Of course, there's the 6.6-liter Duramax turbodiesel engine for shoppers interested in more power and torque, but the truck also offers a heavy-duty trailer package, 4-wheel drive, power adjustable pedals, and front and rear park assist. Shoppers can also add high-end safety features such as a lane-departure warning system and forward-collision alert.

Chevrolet Silverado 3500HD -- The Silverado 3500HD is mechanically identical to the Sierra, and it looks almost the same, too. Check out both pickups, as they're highly similar, though the upscale Denali trim is unique to the GMC.
RAM 3500HD -- The heavy-duty RAM 3500HD is endlessly capable thanks to its huge engines, its wide variety of configurations, and unique features such as self-leveling suspension and a manual transmission. But the latest Sierra is far more refined than the RAM.
Ford F-350 -- The increasingly outdated F-350 isn't as refined as rivals such as the RAM, the Sierra and the Silverado, but with a new model on the way, it may be a better deal.
