In a house, a refrigerator will go 24 hours if the door is not opened. Anyone that lives in Florida with the storms and hurricanes can validate this.
Florida is humid, not very hot, so the experience can wary.
One summer I took our motorhome to Las Vegas, where we slept in hotel, while mh was on open parking lot.
At 10 AM official thermometers were showing 125F, outside temperature on parking lot was 135F, while lot of plastics inside motorhome simply melted.
Touching lock exposed to sunlight with unprotected hand meant visit at ER.
Sure when you drive motorhome, you keep it cooled this way, or the other, but 1 hr stop for shopping can do a trick.
With today's technology 800W inverters sell for about $50, extra battery IMHO is not necessary and most of TV today come with 120 amp alternators, so supplying recharging power pose no problem.

Doubt it would be 120 inside the MH going down the road. Even after three hours, it will only be 1-2 degrees warmer. If I did not have power, I would cool the refer section down close to 32 degrees and then go all day without powering it, opening it, or worrying about it.
OP, you do not need an inverter, especially since you run your generator some of the time and do not boondock.
Modern refrigerators take minimal power, but is still take some calculation.
I did have vintage Airstream with bad refrigerator and instead of spending big amount of money for RV refrigerator that nobody make anymore, I bought $120 small 120V refrigerator.
I measured it to draw 1.2 amp so even with single battery and 1000W inverter it would run for several hr on trailer battery alone what converted made 11 amp @ 12V.
Then when in tow the 30amp charging circuit would supply power to spare.
I would start with buying something like "kill a watt" meter and going to appliance story where you can plug it in and measure the actual power consumption. The factory ratings are usually on conservative side.
