WFCO Converter
At the suggestion of a member I tested my converter with the following result: No shore power, no generator: 12.2VDC Shore power (110VAC) : 12.5VDC Generator power : 12.5VDC ...

The battery voltage went up so that means the converter is working , likely at 13.6v. Wait a couple of days and the batteries should be recharged with the voltage at 13.6
Then remove 120v input to the converter and battery voltage should drop to about 13 and then settle at about 12.75 (or less if they are sulfated)
Shouldn't I be showing at least 13.6 VDC at the battery when plugged in to shore power or with the generator running?
It depends on how much current is flowing. If your battery is low (which it seems it was, based on the resting voltage), the converter can easily be operating in a current (or power) limited mode rather than a constant voltage mode. In simpler terms, it can't supply an unlimited amount of power and so under high loads the voltage sags from the setpoint.
It is also quite possible that there's some voltage loss in the wiring between the converter and the battery, which would also be particularly noticeable with high charge currents.
