I strongly disagree about "buying dirt" as a generally good idea for a vehicle dweller. If you buy dirt you have ongoing property taxes and rules. You can't just park your camper on your land legally, unless it's specifically zoned for "anything goes"... and I frankly don't know if that's true anywhere. I know in the west that isn't the case, at least anywhere you'd like to be. You may get away with it so long as no one complains, but you won't be legal unless you have a septic (at a minimum) and get the proper paperwork, inspections, pay the fees, etc... and that is assuming that campers are even allowed as dwellings. Plus then you are stuck in one spot... with neighbors.
Why not do it for free on the bazillion acres of public land in the west? You have to "buy the mountain", you already own the right to park on all of them! 20 years ago I parked on NF and BLM all the time (13 year stint), did not pay any attention to limits, and never once saw a BLM ranger, and was never told to move by a NF ranger. I was in remote areas most of the time, but if I found a nice spot I'd return to it for months. But even if I obeyed the letter of the limit rules, it wouldn't have involved a lot of driving.
Just because you are living in a vehicle, doesn't mean you have to put 15k miles (or more) on it per year! You hardly need to drive any more than if you were planted on a piece of dirt as a home base. If you like to travel around, then you are going to do that regardless.
Of course its not a good idea at all for the majority of Van dwellers, that's not there goal. Sky and I were simply discussing what we would like and its quite possible to live off 700 a month and own land.
That's why you buy dirt that fits your needs, like no rules and no issue living in your RV on your property. In my case as land becomes more and more expensive and things get crazier and crazier a peace of land will be of great benefit to my children and grand children. I think it would be nice to also offer it to van dwellers passing through. If I can pick up 5 acres of land for under 50k my taxes would be ~$200 a year in WV and the only rules i need to follow is having a septic tank if I build a house and don't shoot anyone. Otherwise anything goes in WV.
