Prudhoe Bay, Alaska, home of Delta Leasing LLC, is located 250 miles north of the Arctic Circle and is not a typical job site. With an average annual temperature of 11 degrees Fahrenheit and winter highs deep on the negative side of zero, Polar Vortex isn’t a phenomenon, it’s simply another day.

Delta Leasing counts on more than 400 GMC Sierras 24 hours a day, seven days a week, and 365 days a year to provide premium vehicle service for its oil field support clients. It’s a business that takes the GMC mantra Professional Grade to heart. 

Delta said it has opted for the GMC Sierra 2500 HD because of its exterior design, comfort level, and, most important, its toughness, and ability to take off-road and harsh dirt road abuse. Some of the trucks never see a paved road.

The cabin of the Sierra regularly serves as a mobile office to both Delta Leasing and its clients. The new 2015 Sierra HD features a fully redesigned interior with enhanced comfort, smarter technologies including the latest-generation of the GMC IntelliLink infotainment system, more storage compartments, and more plug-ins for electronic devices, according to GM. Delta is awaiting its first batch of 50 new 2015 Sierra HDs and said it is most excited about the increased rear legroom and overall improved functionality.
