DC Voltage Readout or Bad Voltage
I have an 04 Winnebago Ultimate Freedom Diesel pusher. When I look at the voltage readout on the inside wall, it starts out at 11+ volts. I turn on some lights and the reading rapidly drops, and so...

You are not measuring "battery voltage staying up" You already said when not plugged in you still see 11 volts on the "inside display"
With no 120 from being plugged in, the inverter- charger cannot make any DC, so all you have left is battery for DC--that s your 11 volts (batteries near dead!) Your alternator charging is working though.
You need a multi-meter to check voltage in different places. Battery posts (the real battery voltage) and at the DC terminals of the inverter/charger.
Some inverter -chargers need to have the charger "enabled" while others seem to enable themselves automatically. If you have 120v in the rig and no voltage at the charger terminals, it is not "enabled"
