If your next heavy-duty pickup needs to be as sophisticated as it is competent, the 2018 GMC Sierra HD has the power and technology to tow and haul like a champ. Denali models offer unsurpassed levels of luxury, while the All Terrain X model is the most off-road-capable Sierra to date.
A number of half-tons now offer an oil-burner under the hood, including the Ram 1500 and Nissan Titan XD. The midsize Chevy Colorado and GMC Canyon are also options. If you need maximum towing, you’ll find better numbers from the heavy-duty F-Series and Ram trucks.
