What Happened
Operated by Superior Metal Transportation Inc., Clinton Aluminum delivers aluminum and stainless steel to companies in defense, transportation, medical, and other sectors. It first leased the Mack MD7 in 2020 and now plans to transition its whole fleet to Mack, supported by dealer Brechbuhler Truck Sales.
“Our drivers love the comfort and safety of the Mack trucks. It is their office when on the road. We drive as a fleet around 1,600,000 miles a year, and the Mack trucks are dependable and powerful to haul the weight of our product.”
“When a customer like Clinton Aluminum is hauling heavy materials every day, power and performance is of the utmost priority. Our MD7 model fulfills that need with its strong performance, along with comfort and safety features that drivers depend on.”
The Mack MD Series, built for medium-duty applications, includes the MD6 (Class 6, GVWR 25,995 lbs) and MD7 (Class 7, GVWR 33,000 lbs). Both are exempt from the 12% Federal Excise Tax, and the MD6 does not require a CDL for non-hazardous loads. The cab was updated in 2025 with a larger 107-inch bumper-to-back-of-cab measurement for improved comfort.
Why this matters
The move signals strong customer loyalty and highlights Mack Trucks' competitive position in the medium-duty truck segment.
