I’ve imagined off-grid living much like you explained.  I’ve prepared a list of communities I hope to visit.  You can view the list at https://tinyuniverse.org/community.pdf if you like.  I plan on outfitting a 4×4 vehicle and a camper trailer to travel in spring to several of these communities.  Most of these communities I found searching popular search engines.  This was before I discovered ic.org.  I was amazed at the number of communities in the u.s and around the globe.
