Do you run your RV’s propane fridge while traveling?

Russ De Maris is writing an article on how driving uphill can affect RV refrigerators. He needs your help in developing the story, so would you please answer the following survey? And if you care to comment, please do so below this article.

We appreciate your assistance in this research. And please be patient, as sometimes the poll can be slow to load. Remember, the poll is totally anonymous so we can’t see how you respond.

If the poll won’t open for you, and if your RV refrigerator operates on propane, please leave a comment below as to whether you leave your fridge on when driving or towing it.

Thank you!

Everyone worried about ammonia refrigerators blocking up. its an easy fix take the refrigerator out and turn it end over end (top to bottom ) a few times and the blockage will be gone. tricks RV service people won’t tell you!

As a firefighter, we are trained to not attempt to extinguish an RV fire if the propane is turned on but rather to block the road, evacuate any nearby buildings and stay well back until after they explode.

I have a 1998 Artic Fox 24′, the frig is a norcold that can be run on ac, propane or on auto. When driving I switch to auto and leave the propane on, in a camp w/ electric I select ac, when boondocking i select propane.

No way, too dangerous and it’s bad for the fridge not being level.

Normally I switch to 12v when driving and use propane at night when 110v isn’t available. I don’t know of an advantage of using propane while driving as opposed to 12v. I just figure why use propane that needs to be refilled when the alternator is happy to crank out the required current without a refill. As for safety… there’s an electrical system that can short out and cause a fire, a fuel system, gas or diesel that can leak and cause a fire, not to mention sharing the road with drivers who’s abilities are questionable. Life’s a gamble eh? I live in So. Cal. (earthquake country) but I don’t turn my gas off at night at home, so why turn it off in the RV?

I voted no I have a residential, but actually it’s a Norcold converted with a 12 volt compressor from JC Refrigeration in Shipsawanna, Indiana. Hard ice cream and no more worries about propane fires. I had one in 2008 in another RV.

We normally let it run on propane, but turn it off and run on the generator when going through the tunnels in Hampton Roads or other places where the propane must be off.

Run the propane all the time, fridge doesn’t have 3 way system ( 12v, 110v, propane) or an onboard generator. Invertor won’t run it either. power draw is beyond battery capacity

I tried to use a ‘Pure-Sine-wave” converter to power the 110V side of the fridge but the Dometic fridge still would not run correctly so I gave up and run the propane.

Please reach out to Mac the Fire Guy and other professionals to comment on the safety aspect of traveling with propane on. Also, ask insurance agent if a claim adjuster would deny a claim if propane was left on and a fire occurred while traveling. We all know you ‘can’ travel with propane on…..but at what risk?

We leave our refrigerator on all the time when we’re driving. I would be worried that we would lose a lot of food by turning it off. I’ll be interested to read why the refrigerator should be turned off and how to avoid spoiled food.

We only use while on the road.

I put in a solar system to run fridge during the day and LP at night.
When we travel at night yes we run LP, but for the most part daily drives. upon staying at a site we use the solar to run most of our items, the LP is really only used for heat and traveling at night.

I always run my refrigerator on propane while traveling. It never occurred to me to not to.

My frig is a 3 way but I always run on the inverter when driving down the road.

I have an older RV with a 3 way fridge, run on 12 volts while traveling.

When on the road, I switch the fridge to DC. That is enough to hold whatever temperature it is at.

I almost always tow with the propane fridge running. Have used RVs for over 40 years with no problem. I have the ARP Fridge Defend installed to protect against overheating the boiler when in an unlevel situation and to prevent fridge damage.
i understand the concern of driving with the propane on and have no problem with those who choose to turn it off. My opinion: When comparing a propane system (includes excess flow restrictors, is regulated to less than 1/2 psi and tank size of about 14 gallons) to the vehicle engine (no fuel flow excess flow restrictors, produces pressure up to 28000 psi in the case of common rail diesel and a 40 gallon capacity) I don’t consider the risk any greater driving with the propane on than running the engine.

Diesel fuel doesn’t go boom. Propane is pretty good at it.

Our Little Guy Max has a three way refrigerator but we’ve never operated it on propane. AC in camp and DC while driving. Very interested in your info on uphill driving with fridge running.

The article Russ DeMaris is writing sounds a little vague but I know that Dometic and Norcold both state that driving (up/downhill) while the fridge is on doesn’t affect its cooling ability nor will it cause any damage.
