That might be a possibility if there is no easy 120V connection.

Have you considered getting ice/dry ice to keep the refrigerator cold? My driveway slopes, so I can never run the refrigerator until I leave. Getting tired of hauling all that food out on the day of travel, I started freezing water in gallon and half-gallon jugs and putting them with the food in the refrigerator and freezer up to 48 hours before turning it on (great for home drinking water too). Everything stays nice and cold, only ice cream gets somewhat mushy. I would think that a block or large bag of ice would have the same effect. That way you wouldn't have to worry about your battery dying or your propane running out.
If you are nearby, you can always replace the ice halfway through your hotel stay. Whatever you do, I hope it works for you!

Freeze some water in a container, and use it to help the refer cold.

Curious why you don't level the RV to run the fridge in your driveway? Our driveway slopes a lot. I put about 2" of jack pads under the front leveler jacks and the Bigfoot system raises the front tires about 12" off the ground to level out my RV. Of course the back tires are on the ground, chocked and parking brake set hard.

That way we can put out the slide and chill the fridge while getting ready to go.

One of the best ways to minimize power draw for a fridge running on batteries for an extended period of time is to disconnect the door seal heater strip. Dometic used to have a switch in the fridge to do this but they stopped installing it many years ago. The fridge light and the heater strip can be disconnected by pulling the power wire for them at the fridge control board. I'd recommend doing this with the fridge turned off and NO AC POWER connected to the rig to prevent your causing a problem with the board or getting yourself zapped.

Just a quick update. I ran the gen for 30 mins on each day so the DC volts never got lower than 12.3V even though it was a couple of hot days and the frig was probably working hard. So at least I know that option worked.

Thanks all for the input!

I wish I could, but the driveway is too steep, the front tires would have to be 18" - 22" off the ground. Since I have no automatic levelers, I would have to drive up on ramps, but there are none that are that high plus it would make the MH too unstable, not to mention that the tail end would probably hit bottom. And it's a concrete driveway, so I can't dig it out. I know, it sucks! (I had the house before I bought the MH).

Solar Panel

A 10 watt solar panel (per battery) will handle the fridge and most of the small parasitic draws on the trailer for a couple of days in the summer. For 10 watt you don't need a charge controller. You batteries will last a lot longer because they will stay charged all the time. For storage, disconnect the trailer from the battery.
