everyone here's the question how long is the battery going to last to run the fridge due to a power outage or traveling from home to a destination any input?

Depends on consumption of the fridge, amount of your battery bank and efficiency of your sine wave generator. Very difficult without some serious calculations. I would use yearly fridge current ratings divided by 365. Amount of your battery bank amp/hours divided by 2 so not to draw the batteries down more than 50%. That will get you pretty close to amount of time. Just keep in mind if you do draw your batter bank down more than 50% it will shorten the life of your batteries. JMHO.All that said, if I were going to go to a residential fridge I would would install solar panels.

If you keep the doors closed you can tow all day without much on a temp rise in the frig.Chris

How many batteries, what size and year of fridge, sine wave or modified sine wave inverter. Do you have solar panels, if so how may and what size etc etc etc. A very common upgrade that many of us have done so you are asking in the right place but you need to give us specifics.

Our new MS on order has a 1,000watt inverter specd for the frig use only is that enough?

Two 6V batteries also.

DRV thinks the 1000 watt inverter is sufficient for the fridge only. RVs for Less installed the 1500 watt pure sine wave inverter and transfer switch on ours before we took delivery.

Power outage maybe 2 to 24 hours. Longer if you have solar.

In transit should not be an issue.

That is exactly what we have and it has worked perfectly for 3 full seasons for us. We generally spend about 3 months a year in ours. We have averaged about 7K miles for each of those years. The inverter is a pure sine wave which I think is better for the refrigerator. We have a Samsung RF197 French door fridge with an ice maker. Also, we have an automatic transfer switch which automatically switches the fridge to the inverter when we unplug from shore power and vice versa. A nice feature if you can get it.

We have 2 6 volt golf cart batteries and a 1000 watt inverter. In 90 degree heat, it takes about 3 hours to get the fridge to proper temp and we still have 2/3 battery power left. Once we plug in to the truck, the charge from the truck keeps the batteries from dropping any lower on a trip allowing plenty of power to run the disc brake pump, etc.
As others have said, if unopened, the fridge will stay cold enough for hours during travel.....just depends on how hot it is outside.
If you don't boondock, I see no issue with the residential.
I hated the Norcold in our 2014 Lifestyle that I pulled it out and replaced it with a residential Samsung only after 6 months. BEST upgrade I have ever done on any RV. Phillip

I put a residential fridge in our unit about three years ago. I love it. It is so much better than the Nevercold that was in there. I don't worry about running it when traveling. We have traveled for up to 8 hours in a day without being plugged in and still had ice in it and the fridge was still plenty cold. We don't boondock though.

We've traveled all day several times with our residential Samsung running off our 1000 watt psw inverter and 2 6 volt batteries. The batteries have always showed a full charge when we got to our destination. As Rusty says, the truck will help keep them up. I did some calculations some time back and based on our battery size and with the Samsung running full time we could get about 8 to 9 hours. Of course, the fridge will not run full time so the actual time would probably be far greater. We never boondock so it is not that big a deal to us. We do enjoy the bigger capacity and the consistent temps a residential fridge provides.
