Kenworth’s T370 medium-duty truck offers an excellent turning radius, according to the company. The Kenworth T370 comes with a PACCAR PX-9 engine rated at 350 horsepower and matched to Allison 3000RDS six-speed automatic transmissions. The locking differentials on the tandem axle T370 tank wagons allow for extra traction needed for deliveries in snow and slush, Kenworth adds. Superior Plus Energy Services incorporated about 70 Kenworth T370 medium-duty trucks into its fleet. Stacy Sullivan, Superior’s corporate fleet manager, says the Kenworth trucks have been reliable for deliveries through winter months. In addition, the T370 is available with up to 20,000-lb. front and 46,000-lb. rear axles.
