In 1978, Cherry, along with longtime friend John Schneider, auditioned for the part of Bo Duke on the upcoming Dukes of Hazzard. Schneider ended up winning the part, to which he found much success. A few years later, due to merchandising conflicts, Schneider and co-star Tom Wopat walked out on the show, and Cherry, along with Christopher Mayer, were called in to replace them as Coy and Vance Duke. Cherry and Mayer both made their debuts on Dukes in September 1982. Despite fairly similar physical and behavioral resemblances to the familiar leads played by Wopat and Schneider, Cherry and Mayer's characters of Coy and Vance were not accepted by viewing audience, and ratings for the popular series began to sag during the 19 episodes in which they appeared. By the middle of the 1982–83 season, Warner Brothers came to new agreeable salary terms with Wopat and Schneider, and in February 1983, both of the original stars returned to the show. Cherry and Mayer appeared alongside Wopat and Schneider briefly in the episode of Bo and Luke's return, and then were written out of the show and never mentioned again.
