I'm not speaking for Fran or Dave, but many people turn their refrigerators off of propane operation for travel for one of at least three reasons:
  • They want the propane supply valve on the tank closed so that in a collision there is no open propane line to feed a fire; with no propane supply, the refrigerator can't run on propane.
  • They need all propane appliances to be off when pulling into a gas station (because an operating appliance can ignite gasoline fumes), and don't want to do this (or remember to do this) at each stop, so they just leave it off.
  • The flame blows out - or they are afraid it will blow out and they don't trust the valve to shut off flow - with the air movement of highway speeds, so they find propane operation while towing to be unworkable.

The 12V mode (if you have one; larger RV refrigerators normally don't) is for use while towing, but some people find that if they use that their trailer battery doesn't recharge.

I started this reply, then got sidetracked for a while. In the mean time, Baglo posted essentially the same first two reasons - we're saying some of the same things.

And, you have to shut off the fridge prior to stopping for fuel, going on a ferry or through a tunnel. So, stop, shut down, get fuel or through a tunnel, stop, restart fridge. PIA.
Is this restriction just for propane usage or does it also applied electrical power to?

Yes, but if you want that draft to really work, I think you want the shade open at the top, rather than directly against the trailer wall. It seems like an awkward thing to set up, but if it makes your refrigerator work maybe it's worthwhile.

I've seen this shade idea discussed before, perhaps in this forum.

That may be true but when the metal access panels on my 17b get direct sun it gets hot, very hot. When it's in the shade it stays cooler. Do these units draw in air from these panels?

By "restriction" do you mean the ferry/tunnel rule? This is only for propane, because the hazard being managed is a propane leak in an enclosed space, not the ignition source.

The collision (MVA) issue could be about both the fuel source (leaking propane from ruptured gas lines) and about the ignition source (appliance flames). Powered circuits in the trailer could be considered ignition sources, and would be if they shorted due to cable damage, but I've never heard of this (like electrical systems in trailers) as a serious concern... in part because fuses blow and cut off shorted circuits.

Doesn't apply to electric, but running on 12V while driving deprives your trailer battery of charge, because the fridge is using all the tow vehicle can deliver. Not a great solution.

We just don't feel comfortable having the propane running while travelling...we know most folks do run the fridge on propane while travelling and are not worried about it but it just makes us nervous.

Neither is leaving the fridge shut off while traveling if you have refrigerator temp control issues.

Our Casita's 4.1ci fridge would freeze food sitting on the beach in Florida and Casita' s have terrible venting. We have the 4.3 in our 19. I think Dometic has missed the boat on this new series and the fridges cooling system is inadequate for the size.

I would echo Jubal's comments. The 4.3 in our 19 just does not work when it's hot outside. Elevation had nothing to do with it as far as I could tell...we were headed west across Nebraska and it was as bad in Omaha at 1000 feet elevation as it was in Scottsbluff at 3900 feet. We just carried a cooler in back of the Traverse with a new block of ice every other day. I'm also eager to see what Reace has come up with.
