adding second shore power receptacle

RoyB's comments reminded me of a prior Class C which had a built-in generator. The shore power compartment which held the cord also had a female receptacle which was wired to the generator. The cord was plugged into this receptacle when stowed and you were ready for generator use. If you wanted shore power you simply unplugged and moved the plug to the pedestal. A simple and elegant solution that you might be able to use.
