I'd kind-a hard to decipher part of your post. "It would has 5 battery"????
Now, not sure of what that means but, I can assume it might mean your coach has FIVE BATTERIES. And that would typically mean, it would have two starting batteries and three 12V Deep cycle ones. Or, I guess it could also mean you have FIVE HOUSE BATTERIES. You'll have to answer that one.
But, while I've not had the experience or pleasure to own and operate a residential fridge in an RV, I've read a few reports on just how people operate those. It seems the majority, if dry camping, will run the generator for approximately 2 hours in the morning for various activities, breakfast, coffee and, charging the batteries enough to sustain enough power for the inverter to carry the fridge through the day.
Now, with minimum intrusion into that fridge during the day, i.e. kids opening and closing it a few zillion times for cokes, snacks and what not, most residential fridges will be able to coast through the day without cycling too much so, the batteries will handle normal draw.
Now, they'll do the same procedure at night. That is, run the genny for around 2 hours for prepping for dinner and other chores and, again, charging up the batteries enough to handle the inverter/fridge duties though the night.
I've read a few that utilize that same kind of procedure. Of course, if you're tied into shore power, it's moot point. Good luck.
