Converter: Power from a wall outlet (AC) or generator >> Converter >> Charges Batteries (DC)
Inverter: Coach Batteries (DC) >> Inverter >> Wall outlets in your coach (AC)
Your toy hauler came standard with some sort of converter to charge your batteries. It may or may not have come with an inverter (probably not). And depending on the size of the inverter and how it was installed, it may or may not supply power to each of the outlets in your hauler.
This might be an overgeneralization, but you might be able to tell which is which just by the proximity to the batteries. Your inverter should be physically very close to your batteries.
