I think “Route 66” was patient zero for a certain type of show: the mysterious drifter (or drifters: I can think of some shows with a pair, but I can’t think of any with more than two) come to a town, meddle in the affairs of other people solve someone’s problems, and then move on to the next town. (See: “The Fugitive”, “The Incredible Hulk”, “The Master”, etc. I think TV Tropes refers to this as “Walking the Earth“.)
Amazon Prime has four seasons of the show available. I feel like I want to watch it, and I have tried to watch it. But I just can’t get through the first episode.
Other credits include, yes, “The Master”, “SST: Death Flight”, “Movin’ On” (I don’t think that counts as a “Walking the Earth” show, in spite of the TV Tropes entry, but I believe “BJ and the Bear” would), and “McMillan and Wife”.

In 1972, a crack commando unit was sent to prison by a military court for a crime they didn’t commit. These men promptly escaped from a maximum security stockade to the Los Angeles underground. Today, still wanted by the government, they survive as soldiers of fortune. If you have a problem, if no one else can help, and if you can find them, maybe you can hire The A-Team.
Ahem.
