12 volt system

[mrsir55]

Just got my first larger camper. Went from a pop up to a fifth wheel and I'm trying to find out what should work off of the battery. The owners manual doesn't say.

All the lights, water pump, fridge while on gas, furnace, water heater if you have electronic ignition, and radio. TV and Micro are the only two things that "need" 110. When you are plugged into 110 the converter supplies the 12 volt for all the above and also recharges your battery. The fridge can be set to run on 110 as well to save propane, but it still needs 12 volt to operater the control circuits.

This chart should give you a pretty good idea for a 30AMP Trailer setup

As seen in the chart, the A/C also needs 110V.
