The MAC Trailer Story

From Humble Beginnings to World-Class Manufacturing

Since he founded the company in 1994, Michael A. Conny has grown MAC Trailer Enterprises into a manufacturing leader. Conny started repairing trailers in a one-bay garage more than 30 years ago, and it was through hard work, strategic expansion and a dedication to customer-led solutions that the company continued to thrive. Today, we have employees and plants across the country, a family of trusted brands and a dedicated research and development facility.

Conny started in the trailer-building industry but eventually decided to branch out on his own. With a small loan from his mother, he began doing wreck and repair work out of a one-bay garage.
