A fully charged 12v system sitting idle is 12.6v. However, you said your rv was plugged into shore power and the converter is running. Modern converters are three staged, which will keep the batteries fully charged by supplying approximately 13.4v. This is what you are seeing. If you disconnect the converter, your batteries will drop down to 12.6v (or so).
HERE is a good explanation of how 12vdc in our rv's work. Good reading.
