I do not believe it matters. .I'd not do it.
12 volt systems are very.... Socialist (Each according to it's ability/nees, the Commun form of socialism not to be confused with other forms)
Parked, connected, engine off, the Tow vehicle's isolator should be "open" (isolate mode) and the converter on the trailer should be the highest voltage (The most able) so it will provide charge for the trailer batteries, and lights, fans, water pump et-al that need 12 volt inside.
If the isolator fails. it will also top off the tow vehicle (no damage) this assumes all lead acid batteries .
So no need to unplug if not unhooking. If unhooking, then unplug.
