2023 MACK MD6 Description
THE PEDIGREE: FLEET MAINTAINED & READY TO WORK
This isn’t your average used work truck. This 2023 Mack MD6 is a premium fleet trade-in from a national forklift distributorship. They rotate their service units every two years like clockwork, meaning this rig has seen a strict preventative maintenance schedule and is just entering the prime of its working life.
If you are looking for a "turn-key" solution that keeps your best technicians happy and your downtime at zero, this is the truck.

THE POWERTRAIN: COMMERCIAL GRADE VS. THE COMPETITION
While other manufacturers try to put "beefed-up" pickup truck engines in their medium-duty lines, Mack knows better. This MD6 is powered by the legendary Cummins ISB 6.7L (300 HP / 660 ft-lb torque) paired with the Allison 2500 RDS (Rugged Duty Series) transmission.
Why this beats a Ford Power Stroke package:
• Purpose-Built Commercial Power: Unlike the Ford Power Stroke, which originated in the light-duty pickup world, the Cummins ISB is a true commercial-grade engine designed for million-mile longevity and ease of service.
• The Allison Advantage: The Allison 2500 RDS is a dedicated vocational transmission with a torque converter that handles the stop-and-go abuse of a service site without the "hunting" or overheating common in Ford’s TorqShift integrated systems.
• Resale Value: In the secondary market, the Cummins/Allison combination consistently commands a higher premium and faster liquidly than automotive-based drivetrains.
