Just curious--can you get 12v to the rig via 7-pin with your set-up if the trailer batts are 'dead in the water' for any reason? Will that light up the Magnum?
-With the trailer batts ok, do you mind paralleling the truck battery with the LFPs via 7-pin? I worry about mixing battery types, but I am told here that is not an issue really. What do you do? Thanks.
I have been thinking about this option but not from the 7 pin. The 2016 Ford diesel truck with dual batteries is always there. Front compartment is always accessible so the nose of the truck could be put near. I was thinking something like from that video from mortons on the move that was posted about the comparison of agm to bb, where he showed the cables from engine compartment to rear of truck camper batteries. Maybe big quick disconnects to something permanent mounted on either end in the engine bay of truck & 5th wheel compartment, for emergency purposes.
Or something like this?
