I plainly remember the 2013 GMC 2500 HD manual said the ignition said it cut off current flow when key was off, so as not to discharge battery. I no longer have it now. But I have been wrong before so I'll keep my comments to myself

I'm guessing they would be fighting each other, and I'm not sure who would win, which is why I would NOT recommend it. I suspect MOST of us disconnect the TV before plugging in the shore power when setting up, and vice versa when tearing down.

I installed a relay on the TV aux power wire to my 7-pin conector, with a switch on the dash so I can turn it off if I want to. My concern is stopping somewhere with the trailer (park, museum, whatever), being gone for several hours, and coming back to find out something in the trailer drained my TV battery dry. (All you need is some kid to pull the emergency brake pin and you're screwed.)

Do NOT use duct tape it wont hold. Breaker should be in the box.
Thank you, I will have my trailer back next week. I will check under the belly panel then. Hope it is there.

Hey everyone, just a quick update. Turns out it was bad connection at the trailer plug. Think all of the wiring is working now.

Thanks for all the replies helping me out.

Thanks for coming back and letting us know what it was. It's good to hear the outcome of what was wrong and what fixed it.
