Battery Isolation Plan

I wired in a Blue Sea single circuit battery switch on the charge wire located under the hood of the truck. Normally I keep it switched off except for those times when I will be driving a lot and need a charge from the truck. When I get to camp it is a simple matter of popping the hood and switching it off. On our trip to Alaska this past summer we ran with it switched off most of the time as the solar system kept the batteries topped off. Simple and cheap and avoids crawling under the truck to plug and unplug the camper to the truck.
