Mack Trucks recently organized a ride and drive for journalists at its customer center in Allentown, PA; a 65-acre, 160,000 square ft. location that formerly served as the OEM's research, development, and test facility from 1976 to 2010. Complete with several test tracks and off road courses, the customer center location allowed visiting journalists put three Mack models through their paces: two Pinnacle highway tractors, one pulling a fully-loaded dry van trailer and the other a flatbed unit, along with a Granite model configured as a dump truck.
