Inverter Issue

What is make and model of refer? Is it a residential?
Is it an inverter or converter? make and model?

The fridge 120 is on with shore power but not with the inverter, so maybe a transfer switch issue or else the fridge is just not one of the 120 circuits the inverter supplies? Is there a sub panel? When not on shore power but with the inverter on did any 120 thing work when the fridge didn't? Is the inverter on one leg of the 50 amp and the fridge on the other? ( Not sure that is a proper question--I am vague on 50 amp)

Why do you think the refer is connected to the inverter?

If OP has a residential refer, it would need 120 volts to operate.
I would lay odds he has an LP/electric refer and he has it set for 120 volt operation rather then "auto".

If inverter is active, when you unplug from shorepower transfer switch should apply power from your inverter to supply your fridge if it is automated. Of course batteries would have to be feeding inverter, something is obviously amiss but should be simple enough to diagnose with a voltmeter if you have access to these components. PDI at time of pickup should have detailed the sequence of events when fridge is unplugged from shorepower. By the way, that is a beautiful rig, hope you have many great times down the road.

The refrigerator failed to come on... It appears the inverter isn't working

Measure the battery voltage and inverter output voltage.
Post the results.

Inverter model number would help.

Don't confuse converter/charger
With inverter

You could have a converter only, or you could have a combo inverter converter
But you haven't given us any equipment numbers

Make and model number of fridge
Make and model number of converter? Inverter?

Does the tv work, with out shore power ,? If yes then you have an inverter some where that may not be attached to the fridge
If no, then you do not have an inverter

RV fridge with lp elect our auto
Must be on lp or auto
To make sure it gets cold and it is slow, takes time
RV fridge is very seldom connected to the inverter, although in some model the ice maker it's connected to an inverter
The avg RV lp fridge draws too much power on electric to run from an inverter and only one or two batteries and no generator,,

It has an 18cu ft res fridge. Outside there is a big battery disconnect switch that the OP says he turned to connected. Then the mystery starts about what "on button" he pushed next.

I believe it's an inverter (converts battery power) to power residential refrigerator?? Will try to see what make/model it is tomorrow.

The button I referred too was the one to turn on the inverter/Converter.
