I check water level every three months on my two 6V Interstate batteries. I add very little and I am in warm to HOT climates year round.

How long (approximately) will a residential run on 2 golf cart batteries? I am used to going to the rv lot the night before we leave and start the fridge on propane now, so it can be 17-20 hrs before I bring it back home. I dont think the batteries would last that long.

I know there are a lot of variables but looking for an approximation

How long does it take the fridge in your house need to cool down?
I bet if you turned it on when you hooked up to bring it home by the time you got everything else loaded the fridge would be ready to pack.

Austinjenna - a quick reply to your question: our residential fridge (and 1k inverter) draws 160A over 24hrs. Remember that for lead acid batteries you only want to draw down about 50% before recharging. Therefore assuming your golf cart batteries give you about 200AHr, you get about 100AHrs or 100/240= 10hrs running the fridge without other loads. If you’re driving you probably get 2-3A/hr charging from your truck so that you’re good for going site to site. If you want to overnight you really need the equivalent of 4 GC lead acid batteries.

Doubtful, my storage lot is 2 miles away. It takes a few hours for a residential to cool down

My question was more regarding the run time while not moving. I know the truck will charge the batteries while moving. Mine had to deal with it being in the storage lot and being able to start it the day before so what could I expect for the run time.

I did a test when we first got ours, ran the Fridge for 36 Hours on the two size 31 12V batteries and battery voltage was still at 12.6. Now nothing else was in use so fridge was only load. This is with a Whirlpool fridge, different brands might have a different power draw.

What was the outside and inside temps surrounding the refrigerator?

Fridge was set for 34 and freezer was zero, outside was spring in Western NY, so night time lows 40 to 50 daytime 60 to 70, best I can remember, after all it was 6 1/2 years ago.
