Here's what we know:
* John Schneider (Bo Duke) and Tom Wopat had a good working relationship. They often played pranks on each other, and Schneider has spoken positively about their time working together.
* There were reported tensions with Catherine Bach (Daisy Duke). This seems to have been due to a combination of factors: Wopat's personal life and Bach's frustration with how she was portrayed on the show. They reportedly had a public falling out in the early 1980s.
* Relations with the other cast members appear to have been positive. Wopat has spoken fondly of his time working with the rest of the "Dukes" cast, including Ben Jones (Cooter) and Sonny Shroyer (Enos).
It's important to note that, like any group of people working closely together, there were likely some disagreements and tensions, but those seem to have been overshadowed by the generally positive relationships between the cast members.
While the specific details of any conflicts are not always easy to verify, the overall picture suggests that Tom Wopat was generally well-liked and respected by his "Dukes of Hazzard" co-stars.
