Isolating 12v current to trailer
I have a 6ga wire running from the battery of my TV to a winch type quick disconnect at the rear of the truck and the corresponding connector attached to the batteries on the trailer. How do I isolate...

For $20 you can get a basic 85a relay like yhis one. Connect the trigger circuit to something that's only on when the engine is running. When you turn the engine off, the solenoid opens the charging circuit to the trailer.
The battery separator is nice, but if you have only one battery in the truck I don't know if I want to let it go down to 12.8v before it separates.
