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...

The cleanest connector I've figured so far is the trolling motor 3 pole - + and - from vehicle battery plus + wire to turn on the DCDC charger.
On my pickup there is no need to wire into the cab from the battery. I think I can get where I need to go by using long booster cables wire as it is joined and easy to protect inside loom.
I've seen a video where the owner jumped the DCDC turn on from the + battery cable coming in. He said this works but you have to remember to unplug the tow vehicle or the RV will continue to draw on the starting battery of the tow/haul vehicle.
DCDC chargers are also isolators so current on flows one way from the starting battery.
Again, any I've seen are supposed to be install close to the batteries they are charging.
Yes it would be super convenient to have it on the truck because I have 2 trailers with batteries and a truck camper.... I'm thinking of a weather proof enclosure where it can still cool somewhere near the rear of the truck.
When I'm done wasting time on that idea I'll throw hat on the ground and order more chargers :)
In Europe these are called "Battery to battery" or B2B chargers - which kind of explains what they are for.
