Personally, I enjoy several of the van life youtube channels. It's a matter of finding the ones that resonate with you.
For those who mock them as "fluff" and say they're just people talking to themselves, that's what all the "learning stuff" videos you watch are, too. And those same channels you learn from are also monetized "e-beggers."
Here's what I don't understand: Normal people don't hang out in places they have no interest in unless they think highly of their own opinions. I have absolutely no interest in the Matters of the Heart forum so I don't even click on it. Why? Because it would be a waste of my time and I don't care to rain on anyone else's parade. It's common courtesy. Since this thread is clearly marked as a YouTube van life topic, it's beyond me why anyone who hates them would even bother clicking on it... unless, again, they think more highly of their own opinions than common courtesy.
Not all van life channels are the same. I'm new to van life, only learning about it just over a month ago at most. Those videos have been an invaluable source of information. As with everything else, there are the fakes, the trust fund babies, the nitty grittys, and everything inbetween. As with everything else, they're not a one-size-fits-all thing.
I subscribe to channels based on the folks who own them. I like personable, real people. I don't like the over-exaggerated cartoon characters who act like game show hosts. I don't like the Instagram versions that glamorize van life. (Pooping in a bucket and showering in public isn't glamorous.) I don't like people who ask you insincere questions just to get you to comment but never respond, or interact, with their subscribers. But you know what else I've learned? There's an audience for everyone and I don't begrudge anyone's success.
As for Carolyn, I think she's kind, sincere, fun and tells great stories! When she sticks to van life topics, she's a hoot! When she gets personal and political I simply turn her off because we wouldn't get along for a single minute. But I wouldn't dream of saying anything about it because I would never attack her on her own channel, or frustrate the experience of her 78,161 subscribers.
