I'm in the group recommending rent, wait and see first. I'm very much nomadic at heart, moved often throughout my life to include almost a dozen years overseas. My wife however gets homesick after a few weeks on the road. We're retiring in a few more months and intend to keep the house at least for awhile, and will wait and see how the wife feels about it once we spend more time on the road. So far, the more we travel the more she seems to like it.
As for people I know, my old boss retired a little less than 2 years ago. They had a RV spot up near Jackson Hole, and a house in northern Utah. Their plan was to sell both pieces of property, and live out of their fifth wheel, north in the summer south in the winter sort of thing. After 18 months they decided they didn't like that after all, sold the fifth wheel, put a park model on their RV lot and moved back into their house.
On the other hand, a couple I worked with in the military retired from the Air Force, planned to live a year in their motorhome, then settle back in to a home. 6 Years later while hiking a trail in Arches National Park I ran into them on a trail only to learn they were the camp hosts. Seems they loved the full time lifestyle so much they decided not to settle into a single area, even seasonally.
Safest bet is try then buy if and when you're sure.
