Description
PLEASE NOTE: The truck described below is currently in production with an anticipated completion date of Late July / Early August. Sample pic's are used.
Potomac Truck Center is proud to present an elite commercial workhorse designed to maximize your uptime and redefine your payload capabilities. This 2027 Mack MD7 comes completely upfitted with a premium custom dump body and a stunning, professionally synchronized Viper Red paint job covering both the cab and the body.
Versatile GVW Ratings: Built for Your Fleet
Whether you are looking to avoid CDL requirements or need a full Class 7 capacity, this chassis accommodates your exact logistical framework:
Non-CDL Configuration: Can be de-rated to a 25,995 lb GVW unit, opening up your driver pool significantly.
Full Class 7 Capacity: Can be rated at its maximum 33,000 lb GVW capability for maximum haulage.
Payload Booster: Need even more capacity? A lift axle can easily be added to this truck to scale up your legal payload capacity even further.
Powertrain Excellence: Cummins B6.7 & Allison 3000 RDS
At the heart of this Mack MD7 is the legendary 325 HP Cummins ISB 6.7L diesel engine, pumping out a massive 750 lb-ft of torque.
When combined with the elite Allison 3000 RDS 6-speed automatic transmission (equipped with PTO provisions), you unlock commercial-grade performance that simple gas trucks cannot match:
Unmatched Tow Rating: This robust engine and transmission yields an exceptional GCWR/tow rating, perfectly paired with a tractor package and air/electric lines plumbed directly to the rear pintle hitch plate.
Heavy-Duty Rear Axle: Features a massive 23,000 lb rear axle complete with a full differential lock to guarantee traction on loose gravel, mud, or steep construction job sites.
The Diesel Advantage: Cummins 6.7L vs. Ford Gas (F-650 / F-750)
Why choose the Cummins ISB 6.7L diesel over a Ford gas V8 option?
Torque at Low RPM: The Cummins diesel delivers its peak 750 lb-ft of torque exactly where you need it—down low—allowing you to pull heavy loads out of pits effortlessly. Gas engines require high RPMs to hunt for power, causing massive strain.
Longevity & Resale: A commercial diesel engine is engineered for a significantly longer life cycle under continuous heavy vocational duty cycles compared to a gas block.
Fuel Efficiency under Load: Under a full payload or towing a trailer, gas fuel economy plummets drastically, whereas the Cummins diesel maintains optimized thermal efficiency and lower operating costs.
️ Premium Cab Interior & Body Features
Accommodating Cab: Thoughtfully laid out to comfortably seat two to three people, featuring a high-back Mack-Air driver’s seat and a durable Mordura bench seat with an integrated storage box for the crew.
Premium Trim: Equipped with a satin finish interior trim, tilt/telescopic steering wheel, flat-bottom steering controls, and a Bluetooth-integrated hands-free audio system.
Rugged Dump Body: A 14-foot premium steel dump body featuring high-tensile AR500 steel sides and deck, air-operated side-swing tailgate, and a premium electric mesh tarp system.
With an estimated ETA of late August, this highly spec'd Viper Red beauty will not last long on the market.
Mid-Atlantic & I-95 Corridor (VA, NC, MD, DC, DE): Pintle-ready dump truck, heavy-duty regional hauler, urban maneuverability, I-95 corridor delivery, local municipal-spec, site-prep ready.
Northeast & Tri-State (NY, NJ, PA): Bridge-formula optimized, tight turning radius, metro-ready dump, toll-route efficient, rust-resistant powder coat, tri-state delivery.
Southeast (SC, GA): Sand and gravel spec, coastal infrastructure ready, heavy quarry duty, high-ambient cooling capacity.
Midwest / Ohio Valley (OH): Excavating workhorse, aggregate hauler, multi-purpose vocational truck, municipal stock truck.
Driver Pool Flexibility: Non-CDL 25,995 GVW option, widen your driver pool, Class 7 33,000 GVW capacity, scalable payload.
Upgradability: Lift-axle compatible, expandable payload capacity, future-proof fleet investment.
The Cummins Diesel Advantage: High-torque commercial diesel, 750 lb-ft low-end grunt, out-torques gas alternatives, commercial-grade longevity, heavy vocational duty cycle.Specifications
