RV Fridge not working on campside propane tank
We have a '19 3700LK and we're at a seasonal site (first year seasonal) and started running the fridge off of propane (the elec. bill is insane). When we switch the propane to the camp side tank the fridge flashes the 'no fuel' error (forget the actual error code) and stops running. However, the fridge will run on the back side propane tank. Does the fridge only work off of one tank?

In the files section are the instructions for the auto switching valve in the left side propane compartment.

Does your oven, cooktop, furnace and water heater work from both tanks?
When you turn on the tank valve you must open it really sloooowly. If you open the valve too fast it the internal Safety valve will trip stopping the propane flow (leak prevention).

I switched the tanks and everything works just the fridge when switched over to the campsite tank. So not sure if that's it.

Weird! Each of the water heater, furnace, over or cooktop use way more propane than the refer. Can you describe (pictures are better) the hookup you have for the external propane tank?
I am guessing one side of the regulator is utilizing an Extended Stay type connection to the external tank?

There is no external tank, its the tank that came from factory that sits in the camp side cabinet.

The "right" or "Starboard" side.
Ok, each propane tank has its own regulator.
Both sides go through an auto switching valve.
So the fridge works in Propane mode from the left propane tank (as does ALL the gas appliances).
When you switch to the right propane tank, Everything works ,
EXCEPT for the fridge in propane mode.
I think you need a gas tech with a manometer (gas pressure meter).
