For what its worth, When we traveled from Western NY to Titusville, FL two winters ago, we traveled with the propane off. We only traveled 5-6 hours each travel day so the first night was in Sutton, WV, then we were in Greensboro NC for several days and then Savannah, GA for a night before reaching Titusville, FL. We turned the propane on at each stop to cool down the refrigerator again. We didn't have any problems with those length travel days so RV Gas/Electric Refrigerators will stay cold for at least that long provided you don't open the door.

My understanding is that the excess flow valve only cuts the propane flow by 80%. The GasStop is supposed to cut flow 100%.
Here is Eric at TechnoRv explaining the difference: https://youtu.be/_g38JponlN42022 Solitude 378MBS-R

Not meaning to nit pick, but there are many articles that state that the excess flow valve that is built into the ACME fitting restricts the flow of propane by 90 to 95% instead of the 80% that Eric states in the video. With that being said, I agree that 100% is better.

I was not aware of that. I learn something every day. Can you cite a CRS or law for the allowable post trip bypass flow? I could not find any information on requirements. I did find for residential and commercial applications the manufactures specify around 2% bypass after trip, which now that I want to provide a link - I can not find again. I could not find any specifications for excess flow valve for portable propane bottles, so I do not know if the above applies.

Had five rv's with propane fridge over the years and always traveled with propane on. Only turned off for tunnels or refueling. Never had a problem. My last Jayco and my current Momentum have residential fridge and I hope I never have to go back to propane. We only camp with full hookups so it works for us. I did have one that did not switch over to gas onetime and after six hrs. it was in the sixties in the fridge and the freezer food was getting soft. Outside temps. were in the nineties so that didn't help. If you travel without running fridge get a wireless thermometer so you can keep a eye on it while traveling. It may get warmer than you think.

For our 2019 Imagine 2970RL 34' Travel Trailer with a typical relatively small Dometic fridge:
- We use battery-powered wireless temp sensors in freezer and fridge, with remote readout: Readout is always on!
- The temperature comments in the PDF mentioned matches exactly our experience in temperature change inside fridge when power is off [PDF link is in https://www.mygrandrv.com/forum/show...ent-(Norcold)]
And
- When traveling, propane is always on except when going through tunnels (or some other location) that require it off
- We cool down fridge with electricity at least 12 hours before we get on the road. Trying to cool it down from scratch using propane has not worked for us at all.
- Before starting out after not using it for days, make sure the fridge is actually running on propane. Clear out air from the propane line by lighting the propane stove, then shut off stove after it lights. Otherwise the fridge just "clicks" trying to light propane that has not reached the fridge yet.
Love the idea of an inverter to power the fridge -- we need to look into that!
Things may be different for "house-sized" refrigerators.
YMMV,
