BTW: The cabinet under my TV came with a receptacle in it that is the only outlet on the breaker for that circuit. I hope you're lucky enough to have the same setup.
Excuse me! RVs may be covered by the NEC but that doesn't make the backstab outlets without an enclosure any safer to use. They're just a piece of cheap junk unfit for use anywhere. A $0.50 cheapo duplex outlet in an enclosure from the one the big box store would be much better and safer way to go - especially for a high draw circuit.
