I seem to think I read somewhere three yrs ago when I got my little camper that one should unplug the trailer from the tow vehicle when camped to avoid also running down the vehicle battery if the trailer battery gets low.
This true or bogus?

If all your trailer lights (call them off grid lights i.e., reading lights, pumps, USB usage and so forth)'are drawing 12v from the TD/CT's house batteries, then again, there is no drain on the TV's battery.

For the above scenario, short term.
Nothing detrimental occurs leaving both batteries connected.
Just dont park the car & leave them plugged together days on end.
