I freeze 15 to 20 water bottles at home and put them in the fridge and freezer section to help it cool. Remember a full fridge is a happy fridge and you have nice cool water all weekend. You also can start it on propane a day early. They actually do not use a lot.

We freeze bottled water and put it on the door, fill fridge with cold food, turn on and take off. This method has worked so far. The frozen waters serves like an old fashioned ice box until the power of the fridge catches up.

Don't cool it using your battery. Start it on propane a day early. Ice helps also.
I monitor my fridge temp using a remote thermometer from Walmart, less than $10.
See my thread in the fridge section.

The problem is the fridge in the Interstate is all electric no propane

WOW I didn't even know they made a non-propane fridge, 'learn something new everyday'.

I usually cool the fridge down the night before by having my Interstate plugged into a 120V source. I also add some frozen water bottles. I don't think it would take more than 2 hours for the fridge to get down to temp when you drive. But you may have difficulty keeping it running all weekend on only the coach battery if you are not driving or plugging into 120V. In my experience the coach batteries will be flat in two days just from running the fridge. Of course you can run the propane generator occasionally over the weekend if needed to keep the batteries up.

The trick is, make sure the inverter is set to "charge only". That forces the fridge into 12vDC mode, which is more efficient in its use of power. By doing that, I've started the fridge to let it cool down as much as 36 hours in advance of the trip, without depleting the house batteries below 65%. Side noteó I don't usually cool down the fridge that long; my departure was delayed on that trip. Usually, I'll start the fridge the evening before, and pack the fridge the morning I leave, so it's only on 12~15 hours in advance.

Anyway, the way the Nova Kool fridge is set up, as long as there is a source of 120vAC power, the fridge automatically switches to 120vAC even though it's less efficient in that mode. Any source of 120vAC power, including the inverter. So the only way to keep the fridge in 12v mode is shut the inverter off.

I've debated unplugging the 120vAC cord altogether and using the fridge as 12vDC only, but I haven't been motivated enough to tear open the galley cabinets to reach the electric outlet. Even though someone kindly told me (here on the Forums) how to remove the microwave so I could reach the plug for the fridge.

On the non-wardrobe Interstates, you can unplug the fridg by opening the tilt-out tray in front of the sink so it only runs off of 12v. As you can see in the attached photo, there are 2 single-plug outlets; one for the fridg and the other for the microwave. The outlet for the microwave only works when the Interstate is plugged in to shore power, and the outlet for the fridg works when the inverter is turned on. What I'd like to know is why AS went to the trouble of running 2 circuits there. Maybe AS didn't want to run 2 appliances off of one circuit, but it would have been nice if the circuit for the fridg also worked only when plugged in to shore power (as Protagonist mentioned above).
