RV 110V sockets are insulation displacement types. The romex wire is pushed between two forked pins to push through the insulation and make the electrical contact. They can work loose and open. I had this problem in my old fifth wheel. I found the problem in a working socket that had three romex connections on each pin. The top wire was worked loose over time. I replaced the socket with a shallow old work home style box and socket. I started with all non working sockets and then the fun began to find the problem socket.

I also had a second problem with a connection in the electrical box under the slide. The twist connector worked loose between the romex and the stranded cable wire.
