Propane on for 3-way fridge while underway?

Can't find anything in owners manual addressing having propane on while towing.
Manual says using 12V is not to be relied upon for initial cooling.
Cooling the night before does not last long enough. Arriving at camp site with warm fridge takes until morning to get cold. Like to be able to arrive with unit cold.
Is it safe to leave fridge on propane while underway?

Just be aware of where your pilot light is in relation to an active gas pump when filling up.

On my camper the pilot light tends to blow out in a bad wind so I never trusted it on the road. However because my camper sits in offsite storage I stick with a cooler and throw everything in the fridge when I get to camp along with a frozen jug or two to keep things cold until the fridge manages to cool down to temp. I never tried my 12v as I was always warned to turn it off if you plan to stop for an extended time or else you could have a dead battery on both the camper and car if your not careful. However Many people I talked to have precooled their fridge using 110v power the night before And switch to 12v just before setting off.

I do. You can prechill on A/C and switch to propane or DC for driving if the controls for doing so are on the back of the fridge (that is, the exterior of the popup).

Some popups only have fridge controls on the inside which limits options...

We do tow with the LP on with our TT, as do our friends with a 3-way fridge in their Casita. They discovered that their tow vehicle cannot run the fridge and charge the trailer battery, and pops a fuse in the TV. We would love to tow without the LP on, but our fridge will not hold to a safe temp for the length of our travel days. It can reach unsafe temps in an hour on a hot, sunny, day, or longer on a cloudy, chilly, one, but still sure to be not safe. (I now have a medication that needs to be kept at refrigerated temps, so that just adds to needing it to work.) We have a max/min thermometer to keep tabs on things.
We stop and turn the fridge off before stopping at a gas pump, and turn it on again afterwards. It's handy when the gas station has a large enough parking area to do that right there, but that isn't always the case. There are also some places, such as tunnels, where it is prohibited. I've seen some claims that it is prohibited by states, but I have yet to find any widespread prohibition.

Have yet to use the propane option on mine, that being said, I have refrigerator on 110 I until I hitch up, then switch to 12v for underway. Have yet to have a TV or other battery problem doing it this way. Sounds like gas is the answer for you while underway.
Cheers, David

We pre chill at home from 110, switch to 12V to drive, switch to propane when set up- agree it’s not as cold as we want so we add 4 frozen water bottles to help it get there. Seems to work for us. When we finish camping we leave the fridge with a dozen or so water bottles so they help with the pre chill - I try to do that 48hours ahead of leaving. As there are no clear regulations on driving with an open flame we chose not to as I do not want to stop prior to getting gas every time. But just like everyone else says you find what works for you
