Lightbulb Battery length with solar

I have question that I don't know how to figure out and don't trust sales people.
I have a 371FL with dual batteries and a 190 watt 30 amp solar charger.
I also have a Insignia Residental Fridge and a 1000W inverter.

My question is how long will the batteries keep it running (excluding the solar) I was told if cold hours if has to get cold about an hour. I am not sure the hours is true but the hour seemed more logical to me.

Now the other question is if it is sunny day and the solar panel get's full sun light how long would it keep the fridge running (during day). I guess what I am getting at would the solar be like being plugged into a 30 amp plug to charge the battery and keep the inverter running and fridge?

Since I am new to the residental fridge have no exp with this. I miss the gas/electric but do like how big this one is.
I ask because wondering if in morning before trip I turn the fridge on so it can begin to cool for couple hours before I hook and book if it would in fact keep running or drain batteries to much and would have issues with landing gear because of low power. I know I can connect camper to truck plug but in past that has not always worked until i let it run a bit before I tried to use the electric landing gear.

Any help would be appericated.

If you don't trust sales people you have come to the right place!
You'll be amazed at the answers about electrical and solar.
You will also be confused!

Not enough information. There are a lot of variables.

Get the watts for the fridge.

Questions. Type of batteries. Likely you do not have enough or the right type. Free batteries from the dealer seldom are good ones. With two you likely have about 100 ah available. Since a big refrigerator can use up to 10-40 ah per hour. Not long.

Residential fridges are energy hogs.

Converting battery power to 110 ac is accomplished with an average inverter being 80% efficient. Also. On standby they consume 1-2 amps per HOUR.

Solar requires space. It is reported that on its best day a 200 watt panel could produce 50 ah. You likely need more than three times that.

1000 watts would be swell.

Generally, the tv provides minimal power while traveling. Not enough to run the fridge.

I am assuming a normal truck and fifth wheel.
