New propane tanks have a valve in them to detect a surge of gas ( as might occur in an accident where a hose is severed ). Shuts down propane instantly.
You can even activate this valve by opening the tank too quickly.

I don't run my fridge on propane while travelling. It's not the propane that concerns me but the hydrogen used as part of the refrigerant. If the cooling system is going to fail, it is more likely to do so while bouncing down the road. The possibility of the cooling system rupturing, high pressure hydrogen gas being released and an open flame to ignite it is not a risk I'm interested in taking. Raz

...
And what if all the shaking of the trailer loosens a gas line just enough, or creates a hairline crack, which allows a slower leak, and the trailer fills up with propane.. and the propane alarm that you were so smart to install sounds. but at 65 MPH you don't hear a thing.. UNTIL...

But I do run it on propane at times, I just try not to do it unless I really need to. I know that there is a risk. There is also a risk to eating food that got too warm.

Without any hard evidence is the way most people study this issue. And thats why the debate goes on, and on, and on.....

Clarification: I'm informed the valve is actually at the end of the hose that screws into the tank. More or less in the same place, effectively doing the same thing.

Most dangerous thing you can do is hook the trailer to the tow vehicle and turn the key.. <_<

Ok, so how many of you close the valves on your propane tanks when travelling?

GBaggs is right. Getting into the tow vehicle is the most dangerous thing you can do. Running on propane, not.

I've never traveled with my propane tank on...never will! (Unless it's an absolute oversight/mistake on my part). That's one danger I can avoid. I disklike propane so much, I went all electric. Now I only use my propane tank to burn my "Lil Red Campfire". EDIT: I do boondock once a year at a model airplane flyin where I burn propane in the daytime (wh & fridge) and a gen at night!

I've ran my Dometic fridge (1.9) on 12v with EVERY travel since I bought my 13' Scamp in 2010. I pull with a 4 cyl Nissan Frontier. NO problems with a dead battery at anytime.

(Why does this thread seem like dejavu?)

So when do you use the 12V?

Because new people join all the time.
Ever wonder how they get all those full propane tanks to the exchange centres? Or how they fill that huge propane tank at the filling station?
Ever wonder where that electricity comes from?

Your comment above is giving me a dejavu moment

As you well know due to your dejavu moment: that not everyone is as successful as yourself at running their fridge on 12V. Including myself who also tows with a newer Frontier with a full factory installed tow package.

The reasons for that were more than well explained on another recent thread which was actually titled "Battery Not Charging" no indication the topic was in fact the same old 12v fridge issue.

I have owned more than one 3 way fridge in the past that I was never very successful at running on 12V no matter what I was pulling the trailer with. Always landed at the campsite with a battery less than full which is not a good way to start out 4 days of dry camping.

Now I have had a 2 way that automatically switches its self over to propane - no need for me to go out and light anything I see no reason to bother with owning a 3 way.

As others have suggested if its a newer fridge and propane system, it is far safer to run while towing than it is to carry around a gas generator & the fuel cans needed to feed it, not to mention running it beside your trailer.

You mean ammonia (NH3)? Hydrogen is not a refrigerant. Ammonia is not explosive.

I'd be more worried about the flame blowing out and raw propane (C3H8) filling the trailer. That is explosive.

Welllll....if we could capture HALF of it created right here in the FGRV forums and put it in discharging bottles, we could start our own business and do away with propane completely!

Or gas fumes from filling up at a gas station reaching the flame.

Ours stay closed until we're ready to use the propane.
