The vast majority of ownership parks are in the South because that is where the snowbirds congregate. People can go to all corners of the country in the Summer, but good winter weather exists primarily in Florida, South Texas, Arizona and California.
As for ownership parks, they can be great or they can be an absolute nightmare. Remember, the dues paying owners have to cover all the expenses of the park. If a bunch of people just quit paying dues (and it happens, a lot), suddenly your share of the parks operating costs start to skyrocket.
You are also going to be a subjected to one of the toughest HOAs there are. RV owners tend to have very strong opinions, one way or another. If a voting majority want to build rec centers, pools and provide free liquor, they can vote an assessment increase and you will have to pay it, regardless of whether you were in favor or not. To the other side of the scale, a voting majority of cheapskates can prevent the roads from being repaired, can let the landscaping and grounds go to heck, all because they don't want a $25.00 a year increase in the HOA fees.
As for real estate with RV Ports or garages, they are a bit harder to move because they only appeal to RV owners, which is a very small subset of home buyers. For 99% of homebuyers an RV port is either worthless or an eyesore that will prevent them from buying an otherwise perfect home. With the absolute right buyer, it will be a plus, but absolute right buyers have a habit of not appearing when you really need to sell.
They are both great ideas if you enter into them with your eyes wide open. Jump in the deep end without research and full knowledge of all the pluses and minuses, you could lose big-time.
