Fulltiming across the USA.............on your own land?

One maybe two sites, I could see. My parents used to have land in northern Michigan but it was one site that got used many times per year.

A dozen, seems like way more hassle than it's worth. You still pay property tax and have to maintain insurance. Then if you want utilities, you have to get them turned on and off. Just keeping track of everything would be a part time job.
