Mack MD Series Fleet Financing

Medium-duty trucks carry a different kind of freight and serve a different operational profile than Class 8 tractors, but the financing math is the same: units sitting out of rotation cost money, and replacing or adding trucks has to happen on a schedule the business can support. Mack's MD Series, including the MD6 and MD7, brought a purpose-built medium-duty option into a brand previously known almost exclusively for heavy vocational and Class 8 work. For fleets already running Mack heavy iron, the MD Series is a natural fit for urban delivery routes, service bodies, and local distribution without switching to a different chassis brand.

We finance Mack MD Series trucks in all body configurations: straight truck, box body, stake bed, flatbed, service body, and utility configurations. The minimum transaction is $50,000. MD Series deals typically run $65,000 to $120,000 per unit depending on body type and spec. New and used qualify. B and C credit are considered. Application-only approval up to roughly $400,000 keeps single-unit transactions moving without piles of paperwork. Bank statements cover the rest. Funding averages one to two weeks from approval.

Mack introduced the MD Series in 2019 as a Class 6 and Class 7 medium-duty offering, filling a gap in the lineup between the heavy vocational Granite and the Class 8 Anthem and Pinnacle. The MD6 is the Class 6 variant with a lower GVWR suitable for lighter delivery and service work, while the MD7 handles Class 7 duty with higher payload ratings appropriate for heavier bodies and regional distribution.

Both models use a Cummins B6.7 engine producing up to 300 horsepower, which is well-matched to the weight class and delivers fuel economy comparable to competitors in the medium-duty segment. The Allison 2500 Series automatic transmission is standard, a choice that resonates well in vocational and urban environments where drivers encounter frequent stops and low-speed maneuvering.

The cab is a conventional design with a practical, driver-oriented interior. For fleets running last-mile delivery routes in urban areas, the MD Series' turning radius and overall vehicle dimensions are designed to handle the tight streets and loading-dock approaches that larger trucks cannot navigate efficiently. The cab-over-engine option is not available on the MD, so fleets with very tight urban clearance requirements should confirm the turning radius fits their routes before speccing the truck.

From a maintenance standpoint, the Cummins powertrain has excellent dealer coverage nationwide, which matters for fleets that cross service territories and need warranty or repair access in markets beyond their home base.

We finance the Mack MD Series with any of the common body types: refrigerated box trucks, dry-van straight trucks, flatbed stake beds, service bodies with tool compartments, and utility configurations. The body can be factory-installed or added by an upfitter after the chassis purchase, as long as the full unit is titled as a single vehicle.

Fleets running refrigerated trucks in food distribution or produce delivery are common customers for MD7 financing. The Class 7 payload allows for meaningful reefer box capacity, and the Cummins engine's fuel efficiency on stop-heavy routes helps control operating costs. We also see significant demand from utility and telecom contractors who run service bodies with aerial lifts and need multiple units financed at once.

For operators with credit issues, the MD Series is a strong asset because the used market is active and lenders are comfortable with the Cummins powertrain's reliability record. B and C credit fleet financing is available on MD Series deals, and the right down payment can often bridge a credit gap that would otherwise slow an approval.

Fleets that financed MD Series trucks two or three years ago at rates that no longer reflect their credit improvement have a straightforward option: refinance to a lower rate and free up monthly cash flow. The MD7's steady residual value in the used market means there is usually enough equity to support a clean refinance without a cash contribution.

A truck fleet refinance on MD Series units can also extend the term if the monthly payment is the primary issue, smoothing out cash flow for fleets that are otherwise healthy but carrying high per-unit payments from a deal done when the business was newer. We look at the outstanding balance, current market value, and the desired payment outcome and structure accordingly.

For fleets looking to convert paid-off MD units to working capital, a sale-leaseback pulls equity out while you keep running the trucks. This is particularly useful for seasonal businesses where a cash infusion at the right time means buying inventory, taking on new contracts, or bridging a slow period without drawing on a credit line.

Many operators pair this with Ram Commercial Truck Fleet Financing, Chevrolet Commercial Truck Fleet Financing, and GMC Commercial Truck Fleet Financing.
