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...

Yes, thanks. I will see how it goes first. It is more like 12 ft one way, but the 7-pin charging wires are more like #10 or 12, so amps will suffer. It is a Truck Camper and camper batts are near the front of the truck bed, so closer. I get 15 amps on the 7-pin now to the camper batt (at first, then it tapers)
The whole point of a DC-DC charger is NOT HAVE TO WORRY ABOUT VOLTAGE DROP ! The charger should be as close as practical to the house battery. The limiting factor will be the fuse that is powering the 7-pin charge wire.

My purpose is not to get more amps (but that would be nice), but to not have the two types of batteries "mixed", which might not even be an issue either. I just don't want to mix them and that's that.
This is even MORE important if you are running different battery chemistries.
