Built for every job.

To handle different applications, the MD Series is available in three models—the MD6, MD6 Low Profile, and MD7. The trucks have innovative features that come standard, and they vary in wheelbase size and dimensions, with transmission options for heavier-duty applications and rougher terrains.

Built for comfort.

Every detail of the Mack MD interior was designed for one purpose: keep drivers comfortable. There’s power steering, tilt telescopic steering column, air suspension driver’s sear and controls within easy reach. If it all feels designed by drivers for drivers, that’s because it was.

Built for uptime.

From purchase to maintenance, your local Mack dealer will treat you like family—with personalized attention and the support you need. And our Geotab® system will provide the intelligence and data to help you operate with enhanced safety, cost-efficiency and productivity.
