 +* People who can camp in driveways can cheaply run shore power to the van with an extension cord.  
 +* people who weekend camp can [[https://www.reddit.com/r/vandwellers/comments/hkvuot/agm_charging_for_weekenders/|charge the batteries from shore power on their return]], augmenting with alternator, solar, or generator if needed
 +* people who drive hours each day (delivery, trucking, etc) may be fine with [[electrical:12v:b2b|DC-DC charging]] alone.  This also applies to lithium chemistry batteries
 +* people who spend long periods off-grid will probably want a robust solar install
