Automotive Electrical Lizards ..... ah Wizards on the list,

Just a crazy brain storming idea;

Four Optima Yellow Top Batteries wired in Parallel .... no separate starter
battery.

A " Off line" Portable Battery Jumper Starter" for emergency starting.

Work ..... ?
Not Work ..... ?
Do Different .... ?

Pertinent Assumptions

1. Daily trip driving 2-4 hrs if that.
2. Several days dry camping 3-10
3. Off line Gas 1000W generator w/Battery charge capability

Note .... thinking about a solar assist panel .... but would have to be
ground based ... roof has pod & kayak.

P/S ..... don't even ask, why 4 batteries.
