Just as a post note. Mice don't care if you are living in the RV or not. One time we had a mouse climb up the electric cord and made it over to a slide, chewed through the rubber slide gasket and entered. He lasted 3 days before I got him with a trap under the sink. I now have a large inverted plate around the cord, similar to what they use on boats, over the 50A cord. So far no more trouble.
