The lady is very smart. I admire her abilities. It sounds like she is traveling mostly in western states where it is easier to find places camp. With the current gas prices she will probably have to keep her driving to a minimum.
I did see something that concerned me. I did not like having the batteries in the passenger compartment. They give off a flamable explosive gas. They need to be in an isolated enclosed area. I have seen two batteries explode in my lifetime. When they burst they splash and spray battery
acid all over everything and everyone near them.
