Your coach has a 3 stage charge inverter system - bulk, absorb and float. What charge your battery needs is determined by the system and adjusted as required. There's also a tempurature sensor which monitors battery temps when the charger is "ON".
You "must" turn the charger on by the firefly panel at the kitchen wall. Also there's a shore power setting in the same panel you should adjust to the correct shore power amp setting ( 50, 30, etc.) Other than monitoring water levels on shore power - turn on rear battery disconnect - plug it in and forget about it.
As I said before there's a pretty good solar panel on your roof. It will keep the batteries charged with the battery disconnect off and both door battery switches off. Using shore power make sure your rear battery disconnect is turned on.
One more thing - if the shore power goes out for some reason - you have a AGS ( auto generator start) which can be set to work ( also set on the same panel) in case the batteries get to low ( shore power not on). It will start automatically to charge your batteries to specified voltage.
It's all in the owners manual and will explain it in detail. All done by entering through the key pad by your kitchen sink back wall.
