I doubt you’ll find those that fit this discussion. The back country bush pilots in the “genre” of those YouTubers (someone mentioned Trent Palmer) fly solo, or at most with a girlfriend beside them.Unless it's a four place. Then, one is four to many.
People who fly four are usually on a mission that isn’t all that interesting to the YouTube audiences. The plane is a vehicle to get them into an otherwise inaccessible place, where they can enjoy lifer for a day or a few. Those people don’t get into the NTSB statistics. Not any more likely than other EA-B flyers.
