Probably going to have to add your own. I am.
I use the Blue Sea ones. I have both lighter style and USB style that I am installing. It takes a bit of creativity to figure out where to put them and keep the wiring hidden. Most of the cabinets have false bottoms you can snake wires down, etc.
My 12 volt plug is going on the end of the kitchen cabinet that has the fridge in it, I can get to the wiring from the outside fridge access. Only thing is to make sure it gets sealed up well against CO. For my USB I am tapping into one of the light circuits on the other side of the trailer and making a new box in the cabinet to lay my phones in while charging.
Most of the TV plugs are only rated to 8 amps and are an odd size, I could not get my cellphone car charger to fit in it.
