DC-DC Charging ?
When you add a DC-DC charger from the truck as in several threads about that, does that put the house batts in parallel with the engine batt? (as with normal "alternator charging" via 7-pin) Or is...

So it wants a wire to the ignition circuit to turn the unit ON, but the unit will be back in the camper. It says any 12v source will do though, so I will connect that wire to the house.
I can leave the 7-pin plugged in with the always live Chev input and put a switch on the "ignition" wire from the house to turn the unit on and off.
"The DC-DC will not power on or operate until the D+ ignition cable is connected to the ignition
circuit where it will detect a 12V source to operate ON. The purpose is to toggle the DC-DC
switch on when the vehicle is running with the alternator to prevent the DC-DC from operating
incorrectly with just the starter battery leaving you with a drained starter battery."
