12V electrical question
I am not electrical or electronics educated, but can follow directions fairly well. I have redone much of the electrical in my Toyota Class C and it is time to energize it. I am uncomfortable wit...

With shore/gen power and you starting the truck engine, the isolator will close and tie the chassis (truck) battery to the rest of the system. The voltage regulator for the alternator will most likely keep the alternator from charging and the converter will continue to charge, but it is possible that the engine alternator takes the full load and the converter will stop charging.
In the panel building world, with 2 power supplies that are paralleled and are not designed to be paralleled, one will take the full load while the other loafs along doing next to nothing. The small difference in 'desired' charging voltage will cause the lower voltage unit (even though both are theoretically the same voltage) to simply lower and stop the output.
I've had my truck running and connected to my trailer while still on shore power. Same thing as you've drawn. It is similar to jump starting a vehicle (battery charger + alternator, or alternator + alternator).
