Furnace operates off DC only?

A pilot light style water heater doesn't need 12V.

While this is a true statement, I somehow doubt the OPs 2003 Prowler has one of these.
They tend to be more common in older trailers - my 1984 Prowler had one for example. And what a PITA it was!!

My water heater has separate switches. 1 for DC and 1 for AC.
I couldn't get the water to heat up with the DC switch the night I posted this topic. I also couldn't get the refrigerator to ignite initially. It took about a half hour of repeat attempts before it finally fired up.
I gave up on the DC water heater switch for the night. I tried again the second night and it heated the water just fine.
So whether the difficult to start refrigerator and the no heat DC water heater switch are related in anyway, I don't know, and whether that means I have a pilot light style water heater I also don't know.

This has been a fun thread for me. All input has been appreciated.

When propane is turned off at the tank the regulator will purge the propane in the line which is a safety consideration. So when you turn the valve back on first lite the cooktop which will purge some of the air. Then for me the HW and refer would lite in 2-3 attempts when they purge any remaining air.
