Before you become a nomad and make the huge commitment of selling your house and living on the road full time, I strongly recommend that you try it first.
Rent an RV for at least 2 weeks and preferably a month to try this life before you sell your home and buy an expensive live-aboard RV.
Of course, if you aren't already retired, you need a financial plan for this, too.
My aunt and uncle made the full commitment to the RV life for a couple of years.
They spent most of their time in Florida.
But after that they returned to North Carolina and bought a home in the same area they had lived before because they missed their family and the "normal" home life.
They didn't regret their nomadic adventures at all because it was a dream of theirs, but they fulfilled the dream and moved on to others.
Now they own a small vineyard and make wine.
If you decide to try the RV life, check out cruiseamerica.com where you can rent a nice unit for as long or short a trip as you need. This is a perfect try before you buy option.
There are always tons of RVs for sale, and you might get a great deal and save a ton of money buying used.
Once you become a full-time nomad, you might decide to take part time or temporary jobs at interesting places, if not for the money, then because you can meet the locals and learn more about the places you visit.
Or you might find places to spend time with fellow nomads and become a band of travelers, moving from place to place as a group.
