Ok, yes your right, I meant to say converter not inverter I misspoke. I do understand and realize the difference, I do have a small standalone 400 watt inverter for small needs. What I guess I was trying to get at, is the converter is charging the batteries when plugged into shore power. Electrically thats the same spot (battery and cord) as what is being fed through the umbilical cord from the truck battery and charging system. Just wondering if any issue could be had with both in play. I guess if the truck isn’t running it probably doesn’t matter and current flow could be back to the truck from the trailer while plugged into shore power. Also I would have guessed pin 4 would have been switched through ignition switch so truck battery would be isolated and couldn’t be drained from trailer. But anyway I think I got a much better picture now, on how all that works. So I think I can pick up from here and figure it out. Thanks again.
