Hi Ron

I had the same problem about the fridge not staying lit while driving.

Here is how I fixed it:

Removed outside went plate.  Note the two holes.  The middle one is the
vent
pipe, the one in front of it and off center is the air intake for the
fridge burner.
It is very important that the intake seals be airtight, since when your are
driving
more air than is needed will force itself down the intake pipe and blow out
the
burner.  Removed two more screws so that the inner plate was off too.
Examined
and cleaned the rubber gasket.    I then used a sealant on the gasket and
also
gooped some  around the intake hole, anyplace I thought air other than
where it
is supposed to, could come in.
Put the inner plate back on, making sure the gasket was in the right place.
Gooped
some more sealant on and smoothed it out with my finger.
Put the went plate back on (its a bit tricky)

That's it.  I then lit the fridge and it stayed on while driving, going
through a storm and
it was getting so cold inside ice was being made in the tray!  When we got
home 8
days later it was still lit.

Hope this is of some help.

P.S.  I used a transparent sealant so it would not be noticeable.
