Some routes like tunnels and ferries have restrictions but otherwise don't worry about it.

I would be more worried about running the propane when stopped. Seriously. Because it is heavier than air, LPG can pool up and become a potential bomb if ignited. That probably won't happen when the vehicle is moving - the gas would disperse.

In any case, as already mentioned, I'm much more worried about a road accident.

In mine, I can turn it off at the tank (outside) or just turn off the LP detector, which closes a valve electronically if it is not running.

This is a hot topic in Aus. Officially, you are not supposed to run on propane, but should use the 12v element while driving. That opens up the next part of the equation...is your 12v wiring installed properly, many homes and vans have too light a wire, and too much voltage drop for the fridge to stay cold... so rewiring is done
Some run on propane and just dont let on

What LP detectors have this feature? My older motorhome does not have this and it might be something I would like to add.

Most everyone I know lights the refrigerator before leaving home. Only ones I know having any issues are with the Norcold firebombs in the new ones.

We even run our furnace when going over the passes in the winter. Cab only heat can't keep up.

Our state ferries require the propane to be turned off when on the boats. Coast Guard requirement. Rather silly when you think about it. The galley uses propane and if the RV had an issue it would not have made it to the dock.

It's a CCI Controls "Pre-Tell 3" (just went out and looked at it). Vintage 1991... so no idea if they are still around, etc.

For the longest time I didn't realize it had that valve since I always left it "on" -- until one time it got turned off by accident and I didn't notice, instead, spending 45 minutes trying to figure out why my fridge wouldn't light up. Then I said "hey, I wonder if having the LP detector on matters" and when I turned it on, after it "booted up" I heard the big clunk of a solenoid... and then everything worked

Propane on or off while traveling always opens up a great discussion. There are discussions on the other forums as well. I think since we are presumably talking about vintage rigs it should be mentioned that many vintage coaches have 3 way fridges. AC,Propane,12V. My '90 Rexhall Airex does. While on the road we use 12V and it does well. Just make sure it works before going on a road trip. Drive safe folks. Happy Trails!!

I alway run with it on. I guess it is a personal choice and what you feel comfortable with.

Well, I have to side with HandyBob which seems to be the minority in this case. I shut off the gas prior to driving. It is a safety habit on my check list - for me this is just in case of an accident. Propane, being a flammable gas that tends to pool, is safe if nothing goes wrong. But, the thought of a ruptured gas line during an accident flat scares me.
P.S. I don't think I am overly cautions, I fly planes (some I built myself), I ride submarines, and I often hike to very remote sites around the world - so my nature is not overly cautious, but the possibility of fire in a motor home scares me. The refrig stays cold enough for me when not running during the drive.

OFF in motion. Running on 12v

I'm reading people being more scared of an accident.
Now please tell me how that COMBINED with flowing propane and an ignition source is safe.

Just because you can get away with it doesn't make it safe to do.

Also have the SS-30 auto extinguisher back there for a tad more peace of mind.

My '88 has a three-way fridge like Hoverbug mentioned. The control panel has a wire from the ignition switch. It transfers to 12v if the ignition is on. It also will not let you manually change it to gas for about 20 minutes after turning the key off, about enough time to fuel up without the gas on.
