Lots of variables, and my view is the importance of one variable over another changes as time goes by. We know several members of the Escapees, who have a 'home base' space in one of the Escapees CO-OP's. Some have two or more places. For example we know people who have a site in Eevergreen CO-OP in Cmimacum Washington, and then another site in the Jojoba CO-OP in southern California. Same with a few we know who have sites in Oregon Suthelin's Timber Valley CO-OP's with sites also in Saguaro CO-OP in Benson Arizona.
These are members whom have full timed for decades, and now have a Northern and Southern base. Many have Park Models on their sites.
Same thing happens quite often with Idaho private RV Parks like Idaho, Dakota, Wyoming, etc. - and then go to Arizona, or Alabama, or Rio Grande Valley, or Florida for winter.
I'm rambling a bit here:)! But depending upon the phase you're in. Early phase of more frequent traveling, getting out and going around the country. Vs more towards the later phases with less frequent miles and travels, and enjoying a home base, or two...
My wife and I have kept a Stick & Brick home in San Diego. Now our 'vacation' home, where MIL lives full-time. We're Domiciled in South Dakota, and follow the laws remaining out of California for the times per year required. (We travel 8-9 months a year, and do San Diego check in on MIL and catch up maintenance for her on this 'vacation' home. We'll probably sell it when MIL is no longer able to live their on her own.
As we travel, we're constantly scouting out locations for 'mini home bases'. For example, we like the Prescott, AZ area. And may buy a few acres of land with a home and put a RV Barn on it which includes a living area within it too. (Sort of a combo RV Barn/Casita.). We'd rent the house out, and retain the RV Barn/Casita for our longer term winter home base. (Though it can get down right cold in Prescott, it usually does not have snow stick for any period of time:)!).
We're not golfer's, but see many people that choose locations for home bases that include golfing privileges too.
One other factor we've noted. More people we know have been buying sites at popular winter locations, say Florida as an example - because it can become such a PITA finding a site in a park during peak snowbird season. And many of them have made 'winter friend's' and wish to have a site in a specific park available for them to be with their friends. With the increase in RV sells, and the increase of Baby Boomer's now jumping into this lifestyle in quantity - the demand for sites in popular snowbird area's is only going to increase...
The above ramblings are just some of the many variables involved on why, how many, where, people choose to establish home base(s) - or not!
Best to you,
