The kids left, the first one a long time ago, the second after we gave her an essentially free house inthe town where she grew up. Still, while we traveled more than half the year every year, we kept a home for them to come back to, where we stored all the junk we bought for them that they've not yet decided to abandon, and they pick through from time to time. They come home between moves, they come home in times of trouble, and they come home to take cate of us.
Since my wife died, I travel less, 2-4 months out of the year, mostly to visit my kids, and they visit less often, but stil visit. I keep the home base for me, I have 30+ years of connection with a small city community. I keep it for them, it is where they grew up.
I live in a low cost part of the country, can afford to keep a home base and travel as much as I want, for a small fraction of urban or suburban life. I don't have to break those connections to afford travel, but my travel doesn't have to be full time, and doesn't have to be RVing full time,since my interests are more global. Full time RVing would be pretty much boring for me, because it would mostly be in the U.S. where every city and town is culturally interchangable for another, my experience 20,000 miles a year road tripping 21st century U.S. (It wasn't like this 50 years ago).
If you havedoubts, keep the home base, try the travel.
