When plugged in shore power at the campsite most probably the converter of ac to dc will charge the backup battery bank.
Rv battery draining on shore power.
The crystals disappear when the battery s charged.
All the lamps fans water pump etc still operate on 12 volts dc just that the dc electricity is provided by the converter instead of the batteries while plugged in.
A battery can be hooked up to shore power with a home extension cord in the same way that it is hooked up with a 30 amp or 50 amp plug.
Alternatively the battery could be taken out and charged with a 12 volt battery charger inside your home.
One rv two electrical systems.
The 12 volt system is powered by a battery or in some cases multiple batteries and it powers things such as the start up on your water heater furnace and refrigerator plus most of the lights in your rv s living space your water pump your carbon.

A 12 volt dc electrical system and a 120 volt ac system.
Begin by making sure the shoreline cord is unplugged and that all 12 volt components are turned off.
This solenoid is designed to allow a charge from the alternator to go to the house batteries but will not allow any house or rv 12 volt functions to draw power from the engine battery.
This also applies to batteries in a towable trailer too.
The easiest way to check for a battery drain is to use a clamp on dc ammeter.
If you decide to leave the rv plugged into shore power i would check the water level in the battery weekly.
This device clamps around one of the battery cables and reads directly in amps or milliamps depending on the size of the current drain.
However many chargers provide a constant charge that can deplete the water level in the battery.
Rv batteries are lead acid batteries and have many cells connected in series.
