Expert Reply:
The Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness - Vehicle End # HM47210 can be connected directly to your trailer battery. You will run the Red wire to the positive terminal on your battery, but the white ground wire will connect to your trailer frame, just like the negative terminal of your battery does. You just want to make sure that connection to your frame is free of rust or corrosion for a bare metal to metal connection.
That will give you the 12V power connection you are seeking so you can plug your trailer wiring connector into it to run your interior lights directly off that deep cycle trailer battery.
