Full RVing sort of implies moving around, else the question is about using some type of RV, or substitute like a van or a car, as an alternative to permanent housing.
If moving around, RV is what works, some type of house on wheels.
If not moving around, living in a RV, van, or car may or may not be an economically feasibile alternative to room, apartment, house, or house trailer, depending on location and how comfortable a lifestyle you want to support. Job, health insurance, are sometimes dependent on a fixed address. Things that work in a small town don't always work in the city.
Rent for a parking place with utility connections might not be less expensive than a room or apartment of equivalent size. Some places you can have a room or apartment where you don't need a car to get around, that's less likely for a campground or RV park, unless the job is at your residence.
But if it is about being a nomad, for a time while young, RVing can be the better way, particularly if you are staying away from big cities with transportation problems and housing codes.
I see you are thinking motorized vehicle, which tends to work OK if you can keep moving, don't have to settle for a while and then get around. But if staying somewhere long enough to get and hold a job, I think a small TT is better, gives you a fixed home for a while and a vehicle for getting around. Look at what BeckyIO is doing, I think she is doing it the way I would, though I don't need to work.
