I don’t know what this switch is for. It is next to toilet in back bathroom.

Could be a secondary water pump or water heater switch.

Possibly a switch for tank heaters, if installed.

It is a switch for the engine block heater. Used in winter to keep block warm so the engine is easier to start.

Its for when you really have to go bad. You hit that switch and it blows it out the top of the coach 10 rows over. I use it allot. LOL

It's a circulating pump, I have one in my coach. It keeps the solids mixed with
the liquid. Use it frequently in winter months. Makes for easy dumping.

We’ve never had to start in weather cold enough to need this

I don’t see how that could be the block heater in the bathroom. That is just a strange location and very inconvenient. If that circulation pump is real thing, then that’s a cool feature.

It’s definitely the block heater and located above the engine. Check your 120 volt circuit breakers.

It is certainly like the block heater switch in my coach. The original poster did not say what make and model he has, but since he posted this in the Palazzo forum he probably has a Palazzo. And like many things in an RV it's located wherever it was convenient to install, not necessary to use. In my 2014 Palazzo it's located on the base of the bed which makes perfect sense since the engine is under the bed and all the wiring comes through the breaker panel, inverter and transfer switch in the base of the bed.
