Other than starting the motor (and running the radio?) what else does the 12V battery do?
Oh not much, it just runs the brain box on the fridge, the water pump, the furnace motor, the water heater igniter, the lights, and if so equipped, the inverter.
Other than that, not much that I can think of. :h
To the OP, when it comes to an RV battery, bigger is always better.
A popular choice, with good reason, is to run (2) 6 volt golf cart batteries in series.
If you only have room for (1) battery, again, bigger is always better.
