It's possible, though some people find their flame blows out a lot.
I assume it's considered safe to do, because many RV fridges
are "two way" fridges, meaning they operate on propane or
110V only.  (The Westy's Dometic is a "three way".  A 110-or-
12-volt-only fridge is an "AC/DC".  These are described on
Norcold's site at www.norcold.com - click "Products".)

"Two way" fridges are clearly expected to run on propane when
the RV is moving (assuming you don't have the really long
extension cord, and don't like spoiled food).  I don't really know
about the legality, but I would be surprised if RV manufacturers
were selling RV's equipped "standard" with an appliance (two way
fridge) that was only useful if used in an illegal manner.

Of course, since Mr. Bulley pointed out that anything except
"missionary position" is illegal in North Carolina, one would
have to assume that the "three way" or "AC/DC" would be
unwelcome there as well.
