Yeah, if the RV is driving itself, say, 10 hours a day that's 500 miles. Call it $2/mile to operate--cars today are about 50 cents on average--that's $1,000/day. Maybe that's a bit high, call it $500/day.
You can live as a digital nomad today easily for that kind of money and aren't limited to being on the road or parked at RV parks. I'm not sure I see the attraction of being isolated and on the road all the time even if something else is doing the actual driving.
