Not sure what type of fridge you have. When we had a small pup with a three way Dometic fridge (120V/12V/propane) it was designed to run on 12V from the charge line from the tow vehicle while driving. I tried it once on propane and the flame went out and since that model was manual ignition, it obviously wouldn't relight.

With our travel trailer, we have a two way Dometic fridge with electronic ignition. It is designed to run on propane while under way. Absolutely no problem letting it run when you are driving.

As far as stopping for gas, I don't worry about it because I drive a diesel and fill up in the truck lanes. If I did pull up to a pump that also pumped gasoline, then I would turn it off just to be on the safe side.

That's a VERY good point. My RV fridge is 3-way and is 40 years old. It was meant to be used on 12v while driving. And without auto ignition, and 40 year old parts, the risk of driving with it on propane are greater than the risk for others with newer systems.

Why would risk be greater than newer systems?
Both systems close propane gas valve when flame goes out.
Newer systems will attempt relight but if that fails gas valve closes.

IF it was unsafe then it would also be unsafe to operate while sleeping

You probably could pull a 35 foot 5ver with a half ton provided you had no passengers or cargo.

My max cargo is 1400 lbs so with a 200 lb driver I could tow 1200 lbs of tongue or cargo weight.

It would be kind of lonely though.

It show the difference between reading the specs and understanding the specs.

I wonder if propane powered vehicles leave it on while they are driving?

Schwan's ice cream truck are all propane, engine and freezer section. (look at the size of that propane tank in front of the rear wheel!) :E

The forest service(PNF) here in Idaho uses alot of older RV's for there crews that are working way out.They always have issues with there refer's because know one listens to, be sure the frig is level...Each year they take some of the failing refer's out and burp them aka turn them upside down.They also take them apart and skin them adding new insulation etc etc in the off months.

The quickest fix for some of them is turn the refer on and drive down a real wash boardy road.

Myself,it depends on where I am going whether I turn mine on while driving.If I am going to spend alot of time goofing off unlevel on the way to camp,I leave it off.If I will be spending most of the time in level places or just traveling,I turn it on while on the road but if a wash boardy road is involved like most all of my trips,it is always on.

My PUP is a three way 12v, 120v and gas. My TT is 120v or gas which switches automatically.

I'm the one who has 20 links on this subject, but I get tired of posting them because they're often ignored. Besides, it's so entertaining every time it's asked!

Replying to these threads is an instantaneous way to increase one's post count too.

At least I try to make relevant comments.
