I'd suggest to get a small used travel trailer and try out the lifestyle. If you don't dig it after a month or so, you can sell the trailer and not be out a large sum.
You'll probably not get too many positive responses here since most are into RV'ing with travel or vacation in mind. Also, there is a huge demographic of retired folks on the Forum and us old farts get fussy. Heck, we earned the right to be fussy, lol. The "Full-timing" section of the Forum may give you some ideas about the lifestyle.
A few years back I restored an older TT, outfitting it to endure Winter climes and make it as self-sufficient as possible. The restoration thread is in my signature line, "The Cowboy/Hilton". If you have some building or repair skills, remodeling an old trailer can be fairly rewarding. You can get the floor plan how you need it and make provisions for any kind of weather. It's not expensive but it does take a bit of time.
Again, start small and try the lifestyle before spending those dear dollars.
