The manual for my '91 Westy is EMPHATIC about not driving with the refer
on propane, or even having the tank valve on. Sure, some of this is
probably liability overkill, but still it makes some sense from a safety
standpoint; gas line fittings could work loose, regulators fail, etc.
due to the motion induced vibration. Still, I used to routinely leave
the propane on for short jaunts, and then medium jaunts, and finally,
what the heck, I'll shut it off tomorrow, if I remember it! After a few
months of this, I noticed that the piezoelectric re-lighter would come on
occasionally when I was "jaunting", and shortly after this I noticed it
coming on while stationary. Finally, the refer wouldn't stay lit for more
than a few minutes. When I took it into the local Dometic service
center, they diagnosed it as a dirty burner, due to poor fuel mixture.
Initially, they thought it was due to a failed pressure regulator. But
when the regulator checked out fine, they chalked it up to "just one of
those things". About six months later, the same thing happened all
over again. Brought it back in, same diagnosis: Mystery fuel mix
problem causing dirty burner. Since it was under warranty, I didn't confess
that I had been driving it with the propane on, but I immediately thought
"Hmmm, suppose that sloshing propane could be slugging the regulator
with liquid propane rather than gaseous propane, and MAYBE that's what
crudded up the burner? Since warranty was up in two weeks, I decided to
clean up my act. Since then I've been pretty good about switching to
battery; definitely when it's more than a few minutes, OR when the road
is rough or winding, and I've had no further problems. Hardly proof
positive, but still highly suggestive. That, coupled with whatever
incremental safety advantages I might get, is enough to convince me to
shut of the propane when I'm rolling.
