A last note. If I were to full-time, or maybe even start snowbirding, I would get rid of my 30 foot motorhome (and the car I pull behind it) and get a small (16 to 22 foot) travel trailer. I have a van that can easily move that size travel trailer, and it is sufficient living space.
I say this because full timing for me, even without the need to work, would involve staying in each place I go for some time, a few weeks at least. With a motorhome I would have to pull a car to get around (I have that now) but with a trailer my tow vehicle works for getting around. It is also a less clumsy combination enroute. I've done the trailer thing in the past (RV experience goes back 55 years).
The reason I have the motorhome now is because when I retired my wife and I wanted something for road tripping. It is a 30 foot motorhome because her plan included bringing either of the two children, and their families, along on trips, and we've done that too. Now that my wife is gone, the 30 foot motorhome still works for camping trips (for those I usually need to tow a car to get around) and is a huge amount of room for one long term living. It works for road trips, but so does my subcompact car, tent, and tub of camping gear. Right now the space is a lot more than I need for camping, road trips, or snowbirding. (I have nine seats for travel, sleeping space for eight or nine as mixtures of couples and kids). But it is paid for.
What you are thinking about doing, particularly if you have to work for a living, get around every day, a motorhome is not the best RV solution. You should be thinking about something just big enough to live in (which might be as little as 85 sq ft of a 13-foot trailer) and something to move it around and use for transportation.
Finally, RV living as an economic refuge. Here in the middle of the country, I see a lot of it. Singles in small motorhomes pulling a car; singles, couples, families in travel trailers 16-28 feet, pulled by an old pickup, families having a second car to move people. There are enough low cost places to make it work. Moving with the seasons is also what makes it work. Where I am, I "camp" with these people in spring when they are working plowing and planting, in autumn for harvesting jobs, sometimes summer for road construction. But I don't know where they go it winter, when it gets too cold here to survive in a RV, or most of them, where they go in summer. I sort of assume those in agricultural work follow the planting season north, but that doesn't explain summer and winter.
You are probably not thinking about going into seasonal agricultural labor, I just bring it up because it is a mobile lifestyle where RV living can be made to work. But unless already financially independently wealthy, you need to integrate your RV living into some kind of "move around to earn a living" plan. If you are independently wealthy, don't have to think about working for a living, you would probably not be so concerned about rent being "lost" money.
