All four seasons of the show are now on DVD. Essentially, it was two guys in hot car going across the country. they are going to meet many interesting people and get into all sorts of situation along the way.
George Maharis left acting in 1993 and is now an impressionist painter. He said the series was first shot on the road across the country which was a grind for actors and crew working seven days a week, 16-17 hours a day. They made 32 shows a season back then as well.
The show was budgeted for $100,000 an episode, but he doesn't know how often they met that goal. he left near the end of the third season and was replaced by Glenn Corbett.
