May I recommend “long way up” as well (although they also took a boat). They travel from Ushuaia to Canada, and talked about the Darién Gap, I don’t recall how in depth.
Seconded. Long Way Up is entertaining, interesting and has some incredible cinematography. It's also great that Ewan and Charlie rode all-electric Harleys and the crew had pre-production Rivian's (the with the very first 2 Rivian "production" VINs).
