Caravans, informal gatherings usually held on BLM or National Forest land. They have been canceled for now and are being held virtually.
Another good place to meet like-minded people is

Also take a look at iRV2's sister site,
Class B Forums. It has a wealth of information, especially regarding technical aspects like solar.
