I am not "technically" not a "full timer" in the fact I still own my stick-n-brick house and can return to it at any moment if I want to. But, with that said, my wife and I are away from "home" 8-10 months a year, close enough to be full timers. Although, when "home", we never sleep in the house.
One thing you really, really need to have in order if you are wanting to go full timing, or even long-timimg, is to be financially secure in one way or another BEFORE hitting the road.
Unless you have some unusual skills or some truly unique educational experiences, money and a steady source of income is your single most important concern. Have that figured out BEFORE hitting the road and the rest is easy-peasy. (well, there are challenges, but money comes first!)
My wife and I both had jobs that enabled us to work-from-home. We were both in Information Technology, software development for different financial institutions. Before Covid hit, we were both working from home, but I was required to return to the office a couple days a week.
When Covid hit, everyone was "out the door". Now, prior to that, we'd been taking extended week-end outings and on those days where I could work from home, my wife and I were both "connected" to work at a campground somewhere.
When Covid hit and we were not permitted to return to the building, we hit the road for an entire year working from the camper. It was fantastic. No one knew where we were, no one needed to know, as long as we were connected every day to work and doing our jobs. It was by far, the most exciting year of our lives.
When Covid was winding down, I decided to retire. My wife is still working full time (remote) from the camper. I'm now drawing Social Security, and we have not touched saving at all.
A steady stream of financial security is what will make, or break your experience. It will lift you up, or it will crush you like a fly under a fly swatter. So, first and foremost .... where's the steady stream of money coming from .... THAT has to be worked out first. After that, everything else is really .... well ... somewhat trivial.
Edit: Consider campground hosting as a way to camp free. In exchange for a few hours of work, you can get a free camp site. (this is mostly state and national parks). A lot of private campgrounds have a payment system of some time, in exchange for XX number of hours a week. Some pay a small salary and a free campsite to be camp hosts, others pay better, some provide only a campsite. It's a good opportunity, but it still boils down to ... how much money do you need to succeed.
Work camping is another alternative. Look up "Work Camping" on the internet and you'll get hundreds of things to consider.
But, if you have a specialized skills, like traveling nurse, construction, or auto mechanics, (or something else), you can probably land a new position somewhere. But, every opportunity will take work to find it. Sometimes off-the-wall opportunities happen... like helping on a horse farm or stables, or seasonal work picking tomatoes. The sky is the limit.
But, no matter what you choose, your income is the most challenging item you need to overcome.
