Water is a problem for free campers. Modern vans are either solar powered or use energy efficient LED lighting so that they can go for days or weeks without needing power. Water is the concern, it is heavy and costly to carry and isn’t freely available. We run into one sweet old couple who tell us “We get our water from cemeteries. There’s always a tap near the front gate. I guess you’d call it robbing from the dead.” They laugh.
