By the way, I don't like to have shore power and truck power hooked up at the same time. I don't think it can hurt anything, but I would rather not mix electrical systems. Particularly complex ones.
I blew a converter years ago because of this. I had my F150 TV plugged in and running when I connected shore power. The DC side instantly stopped working. I have made sure not to have both plugged in ever since. New technology or proper fusing may prevent this now but I'm not going to chance it.
I doubt that was the cause, with my truck running I am showing 14 volts on the truck batteries - and 13.2-13.5 on the trailer batteries. The set point on my original converter was 13.7, my inverter-charger is 14. There is so much resistance between the truck and trailer batteries that .5+ volt difference (when running / charging) is normal. And yes, the charge line works, there is a voltage drop when I hit the remote start from the trailer, followed by a slight voltage climb a few seconds later.
All I know is I had 12V in the TT just before I connected (fridge was working)and didn't after. The converter had no output and no fuses were blown. This was the first time I had them both plugged in at the same time. Coincidence? I don't know but won't do it again.
We camped the weekend without it.
