The RV battery(s) commonly called the "house" battery would be the one with the inverter cables on it. There may be other positive wire connections for converter, slideouts, steps, etc, or they may all route thru a single power management system where all the fuses are in a remote location away from the battery location.
The chassis battery, commonly called "engine-starting" battery usually is located closer to the engine, with large #4 red battery cable from alternator to battery as main charging cable.
Are yours all mounted together in the same space? House battery may be more than one, and wired to produce more capacity. Engine battery is usually only one. Some motorhomes have a solenoid to allow the house battery to bridge for a few seconds to start the engine in an emergency.

One set has cables marked inverter + and - connected to it.
