When it comes to selecting a truck model to use in the National Carriers fleet, the company’s president, Jim Franck, is quick to the point.
“Reliability and cost of ownership are key to me,” he said. “The key is to find a truck that gives you uptime, and a truck that drivers like to drive, and that truck has to have a low cost of ownership—otherwise it won’t make you money.”
Franck said he’s found the right balance with the Kenworth T680 with 76-inch sleeper, which has become the “standard” for the reefer division’s fleet. National Carriers operates 670 tractors, of which 70% are company-owned.
“The T680’s aerodynamics, reliability—and that of the Paccar MX-13 engine—coupled with driver acceptance, is what sold us,” Franck said. “From a dollars-and-cents standpoint, we’re seeing a 1-mpg improvement in fuel economy over the performance of our previous standard truck. Our fleet also is now equipped with APUs (auxiliary power units) and idle time has been reduced to less than 10%. That reduction represents about half of our savings—so all told we have a fleet average of 7.5 mpg, with our best drivers getting around 8.”
With most routes south of Interstate 80, National Carriers hauls beef in about 40% of its loads with the other 60% a combination of refrigerated, frozen, and dry loads. Its on-time delivery rate is exceptionally high, testament to the reliability of its equipment and diligence of its drivers.
National Carriers, known as the “Elite” Fleet, began transitioning into the T680 two years ago, purchasing the driver-friendly, aerodynamic trucks through MHC Kenworth–Dallas. The company’s latest T680s are specified with the 455-hp Paccar MX-13 engine and driven through the Eaton Fuller Advantage 10-speed automated transmission.
