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.
Your worried about bringing a 12 volt battery "down" to 12.8?. I suggest that you do your homework.
