I watched a lot of Trent & Allie and Eamon & Bec before I committed to full-timing a few years ago, but it seems both couples have moved on to tiny homes since then. For the record, I found them by searching YouTube for "Things I hate about van life," "Things I hate about my van build," or "Things I wish I knew before doing van life." Searching for the negative stuff seems to get some of the more genuine(ish) vloggers. Also I highly recommend watching a ton of those types of videos if you're considering vanlife yourself!
But yeah, I think that looking for "non-glam" vloggers who commit to regular schedules and good production quality really limits your options lol. "Regular" people don't usually invest thousands of dollars in recording equipment, hundreds of hours into learning how to self-produce quality content, and then however many hours per week dedicated to ongoing production.
A lot of the stuff I liked was when these regular vloggers would interview other vandwellers they met; They always seemed more down-to-earth. And you get the production quality of the vloggers!
