Gentlemen's.... first, thanks for all you're comments.
This customer of mine told me that he drove is old 84 (we are now talking
about an 91 syncro)with the fridge on propane...so, it is possible. i have,
lately pull out more fridge then tou can imagine.... so, in my humble
opinion, this fridge principle is hunted!!! he he he, some works fine and
some don't..why...am not god so i don't know!!!

in my world, i would say that it is quite possible that a burner can go off
when subjected to heavy side wind or whatever... but hey, i don't know!!!

This particular fridge was cleaned, and put back together by the book, the
vent is ok and was put together the way it should be...

So...what is so different about those who can drive with propane ON and
those who can't... wear, gasket leak, bad propane pressure, bad pilote?????

Another thing, propane as NO relation with 12v or 120v operation, there is
no physical reason that the fridge as to be primed with 12V or 120V..those a
separate mode, and they have nothing in common!!! all the fridge i cleaned
do start from warm mode on propane, no need for a 120V primming!!!

Still, i don't understand what you guys mean about positive/negative airflow
from the vent!!!! wind is wind, and i think it can blow the pilot OFF!!! but
still, why some fridge CAN still work on those high wind condition????
Anyway, those vent are 15/20 years old, and in average, are in poor working
condition!!!  what is that isolating plate is doing??? that is my question!!!!

as for me...i don't see the point of driving with the propane ON when you
have a 12V mode?????????????????????
