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.

Hey! I knew that. Well sort of. I didn't know that my tanks had a regulator (I should say I didn't know that it was purging the lines). I've always lit my stove to create success with the fridge lighting. Normally it only takes 2 or 3 tries once I've burned some propane at the stove. This time it took extra time, a lot of extra time. I'm guessing the water heater took the same extra time. My systems all seem ready to serve at this point. Now to choose my weekend destination.

Thanks All.
