You said rv lot...several people leave their rv at our park in Yuma and live in northern states. Many near great lakes or couple in Toronto. Many Over the years with large rv's have picked up a van and enjoy making their way down boondock camping all the way down. When they do get south they really enjoy the size of "large" rv compared to their van. We don't leave ours because in our travels We visit our family all the way down coast.
People that leave them usually leave something in window like alarm clock so who ever is checking on them knows elec is on and ok.
