Description
Gary Mahan, Founder and President of The Mahan Collection Foundation, joins Beyond the Bulldog, presented by Mack Trucks, to share the story of restoring the Mack M100SX and preserving trucking history. From rescuing a heavy hauler that had been parked for more than 25 years to bringing its original engine and drivetrain back to life, Gary explains the work behind a two-year project that was too large to fit inside his shops.
He also looks back on building a quarry and aggregate business, the antique Mack that served as his wedding vehicle, and the relationships that grew into a collection spanning more than a century of trucking. Along the way, he shares how skilled craftspeople, family, and fellow collectors help keep these machines running and their stories alive.
Gary discusses:
• How the Mahan team rescued and restored the Mack M100, including its original engine, sheet metal, radiator, and drivetrain
• Why good people and teamwork were central to growing a quarry business from seven employees to hundreds
• How a Mack wedding truck sparked decades of collecting, restoration, and friendships
• The foundation's mission to preserve historic trucks, welcome visitors, and teach younger generations how trucking supports everyday life
This episode is a look at restoring a remarkable Mack truck and preserving the stories behind trucking's past. Gary Mahan shows that keeping history alive takes skilled people, patient work, family involvement, and a willingness to share these machines with the next generation.
