The reason the refrigerator has a 12 V mode is for driving. If the refrigerator is reasonably well maintained, the 12 V mode works, too. Mine does.

I've read numerous comments in the archives regarding driving with it
lit or not. Not sure which instructions you refer to, but I just read
my Dometic glove box manual and door on 182B. No where did I see
anything saying do not drive with fridge running on LP. I may have
missed it. However. They do make mention, in upper case, of 'never
putting hot food in the fridge'. <grin>
On the last trip, I drove with it on 12V. My 12V system works fine too.
What I'd like, is to have it stay lit even if it gets windy in camp.
On last few trips before doing this recent work, it would blow out on
the highway, and in camp. Even if it was only mildly windy.
I understand your point, but to be clear, there's something wrong with
my fridge (thermocouple? Small flame? Both?). I've read reports of
peoples Dometics staying lit when driving. I've even experienced that
with my 182A. Unless a maladjustment in the LP pressure exists (water
column), and adjusting it corrects the issue, I'm hesitant to invest
any more time, or moreover, any more $ in it.
The other reason it has a 12V mode may be in the event one runs out of
propane while in camp. Kill two birds. Hop in the Westy, get more cold
beer, and propane. <EG>.
