Mystery Switches on 2010 X210 Funfinder Custom Control Panel

[cschlab]

Hi I own a 2010 x210 funfinder.
I have a question about the panel and switches below my breaker/fuse panel.
It labeled and has 4 switches. I did figure out the right most switch controls the canopy lights outside. I also understand the lights for AC, DC, and water heater are indicator lights.
What are the other 3 switches for? I’ve tried to switch on/off but nothing happens that I can see. Not sure why it has a “camera” label. I don’t have one.
what does the digital display indicate?

Any help answering these questions would be greatly appreciated.

I'm pretty sure that panel is something installed by the previous owner!

that is definitely a custom panel. I have a 210x. No such panel.

What they said.
An old DIY install......

My guess is the display is possibly battery/DC voltage(?) You'll need to trace the wiring to discover the purpose of the extra switches.
I wouldn't be surprised if, at sometime, there was a small fan installed behind the refrigerator vent to help the fridge get rid of the heat. Extra switches get installed for things like that.....
