You can live in your camper here in Silver City area of NM but plan on a lot of cold temps in winter months. There are many places where you can park for a fee and many places where you can buy unrestricted land pretty reasonable and live as well.
If I can help let me know what info you are seeking. I am an individual that lives in the country on my three acres with animals.
This area has a wonderful wilderness area and lots of forest land also. So if you are looking for peaceful outdoor get aways or just a great place with a good climate -four gentle seasons - this might suit you.
