You should have two battery systems. Coach which operates 12 volt items such as lights, water pump, refer (12 volt control, and furnace)
Another battery system operates the chassis.
The coach system is charged by converter while plugged into shore power or when the main chassis engine is running.
The chassis battery is in most cases charged by chassis engine. Parasitic loads can drain this battery. It needs a trickle charger to keep it up.
Many MHs are equipped with an "AUX" or "Battery Boost" start button to tie battery systems together so if chassis battery is dead you can jump start it with this switch.
