Miller Industries Inc
A maker of towing and recovery equipment, this Tennessee company builds the wreckers, car carriers, and rotators that haul everything from sedans to semi-trucks. Founded in 1990 by William G. Miller, it grew by buying storied brands like Holmes, Century, and Challenger. The Holmes name traces to Ernest Holmes, who invented the tow truck in 1916 after a friend's Model T flipped into a creek and took eight hours to recover by hand.
