KW T370 all-wheel-drive spec
To ensure its trucks can navigate the rolling and often hilly terrain in various weather and road conditions ranging from bone dry to snow-covered and/or muddy, the Navajo Tribal Utility Authority chooses all-wheel drive as its standard spec. The Nation, covering parts of New Mexico, Arizona and Utah, has most recently chosen a series of Kenworth T370s in both 4×4 and 6×6 configurations to add to the fleet of 80 or so Class 6-8 trucks domiciled at seven different locations, the main hub in Fort Defiance, Ariz.
Two of the T370 6x6s are being used as pressure diggers (pictured | photo courtesy of Kenworth). They’re units with augers powered by an auxiliary engine in the rear of the truck. NTUA uses those to drill holes for power line poles. “We have more than 34,000 electric customers and a lot of territory to cover,” says NTUA transportation superintendent Jimmy Bekis. “Maintaining the power lines is a big job, with about 70 percent of the roads we travel being ‘off-road.’”
