Yep. RV or, my preference, "tiny house". The catch is local laws. Many of us are finding we're not permitted to park a tiny house or RV on our preferred plots of land, including those we own outright. In some cases, it's regional bylaws, in some cases developer stipulations. So, the option to move around as desired is limited.
The wife and I are currently on the road with our older motorhome, dragging our Honda. We are basically full time at the moment, having spent about six weeks at home since the start of the year. I copied and highlighted this great piece of info. since it's not only critical to understand, but important to comprehend the scope of the problem, when locating land where you can set up an RV for long term living. I occasionally follow other forums that gravitate to the homesteader, tiny house, "do your own thing" crowd. It's amazing to see how many members on those forums assume that they have a right to dwell in whatever they chose to (old RV, school bus, tiny house, etc) on land they bought. or they are aflame with righteous indignation when they locate a piece of ground, and stop in the town hall to announce their grand plan, and get politely told to show themselves the door. It's also amazing to see how many totally middle of absolute nowhere places, in the states, have well written and enforced laws, regulations, zoning requirements etc... that specifically prohibit doing so.
The problem is not the member here, who has financial stability and a desire to build a nice tiny house, or buy a five acre patch, put septic, power and water in, then discretely park a nice fifth wheel in woods, for a low cost way of life. The township, fifty miles from anything, that bans this idea, is the place where the down and out, barely getting by type, shows up. They just bought a half acre lot in a failed vacation development from the 1960s, and they got it for $400 on Ebay. They have a forty year old travel trailer that they can barely drag down the road, and they are going to live happily ever after. The fact that getting water, sewer and power to the lot might run $40K isn't an issue, they have $200 to their name and hope to make it till the next check arrives. There is no shortage of places like this in the desert, or in Appalachia, where you can live for pennies, but most local governments work hard at preventing new ones.
