Does anyone know of a company that makes a 7 pin trailer adapter that I can use to connect to trailer and have a 12v accessory plug from same 7 pin socket? I want to plug my trailer into the 7 pin socket on my 1500 but also plug in a 12v frig in the bed. Not wanting to drill through the spray in liner if possible. I know that's the easiest way, but I know you can get 12v from the 7 pin. Problem is I want to utilize a 7 pin plug and have a 12v socket come off the 12v socket at the same time. Hope this makes sense.
