Anything from Yahoo news is essentially click-bait. It's yahoo that is not being honest.
However, I don't think they travel IN the van as far as I can tell, they are not RVers so it's out of scope of this forum, they simply live in a van in a state of poverty and use the savings from that lifestyle to travel. Certainly they are not taking the van to Vietnam or Australia.
They describe themselves as "digital nomads" so maybe they have some internet business, also it appears they actually WORK at these locations they visit as seasonal workers in menial jobs to fund this travel. Not a lot of information...
"For the past two years we’ve worked in numerous cities, coffee shops, libraries, parking lots, National Parks, forests, deserts, roadside pull-outs, farms, river banks, hostels, countries...This photo may seem dreamy, but our life as digital nomads isn’t all sunshine and sandals. We may have traded our desk chairs for hammocks, but finding a work-life balance is always a challenge."
