Off grid with an old caravan

I'm a 46 years old italian woman. I do love nature, my family had a house in the country. I work a little for a nature charity and I have some studies in the matter.I've lived in a camper for 2 year in the past. In the last year, I' ve lived in a sociale housing condo and I can' t stand no more: I need privacy, rain on the roof, nature outsider the door and also change please where to live. A camper living is top expensive for me so I would buy an old caravan to leave in place and sell when I move.

May you help me?

Thank your, Nora
