I'm looking to minimize the work on the LH Alt that charges the front battery and tap into the negative side of the rear battery to get 12v.
The goal is to have the rear battery isolated and protected while allowing it to charge a 3rd deep cycle battery in the camper while the truck is running.
My theory is that if I connected the negative side of the rear battery (or perhaps directly off of the 12v bus on the firewall) I could connect it to this:
DC battery isolator and split charge relay for RV, car, and truck applications
and then I'd have solved my problem.
Any thoughts about this? I know I could go directly off of the front battery, but figured it, and it's alternator are already sufficiently taxed and might as well use the rear one.
