Dudley died Monday of an apparent heart attack.
Throughout his career, Dudley charted 41 singles on the Billboard country chart, including "Truck Drivin' Son-of-a-Gun," "There Ain't No Easy Run," "One More Mile," "Trucker's Prayer" and "Truck Driver's Waltz." He had his only No. 1 hit with "The Pool Shark," a duet with Tom T. Hall.
Dudley was instrumental in helping create the American trucker image prevalent in a number of films and TV shows during the 1970s, including "Smokey and the Bandit" and "Movin' On."
His song "Six Days on the Road" also affected a second generation of musicians, with Gram Parsons, the Flying Burrito Brothers, Sawyer Brown, George Thorogood & the Destroyers and Steve Earle recording their own versions of the classic tune.
