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...

That's an idea. I will see how many amps I get and check voltages before thinking of using different wiring instead of the 7-pin's.
I wonder if the "ignition" wire has to be at the same voltage as the input. Using any old 12v to turn the unit on would work, but would it confuse its little brain if it was a different voltage?
I can jumper the pos input and ignition terminals and put the switch in the jumper wire I think.
any switched 12V supply will work. and no it wont put the batteries in parralel, it is a one way charger that only turnes on when the truck is running if you hook that triger wire to a ignition switched source. I wouldnt put it through a fuse block if you dont have to I would just run a nice cable off the batterys to the charger.
I see you are mounting it in the camper? is there a reason for this? I am going to put one in my truck but was thinking of mounting it in the engine bay so I can take advantage of it for both the camper and the 5th wheel.
