We full time since 2019. We sold our home and have only a 6x10 storage unit with our belongings. Our home had a pool and we didn't want to mess with renting. Now, we love our RV, it feels like home so we are not in a hurry to buy another house. Also, we work on the road so our funds are not depleting. It is true most rv parks charge ridiculous amounts these days. They also charge ridiculous cancelation fees, so I spend hours online and on the phone trying to find those that do not. On average, we stay at about 35 different parks around the country, per year. The quality of the parks we stay at has deteriorated since Covid because we can't afford $80+ per night, or over $400 per week. The price of diesel, and food isn't helping either.
With that said, I would suggest you go on a 6-9 month trip first. If you love it and want to keep going then sell the house. If you decide it's not the glamor people make it to be, then you still have your home to go to. This will also give you a sense for what it'll cost you.
We met a young couple in 2020 with a huge Momentum toyhauler who sold their home and quit their jobs to full time. Four months in they decided they hated it and were going back. Better to be sure before getting rid of everything.
Also, if you need a mail forwarding company, that'll cost over $100 a year.
