OK... now we're getting somewhere... with the aux battery we can keep the
fridge running even if we stop the bus. That makes sense. 12 Volt to and
from, propane at the site (almost no campgrounds here that have 110).
Actually though, my propane doesn't blow out at speed, but then we never get
above 65, 70 tops... no freeways here! Besides you can't drive for more
than about four hours without being back where you started!
Thanks for the ideas.

Well, not quite right... althought he 12v starts up right away with the
engine, it takes about 20 or 30 minutes for the chemical reactions in the
fridge cooling mechanism to get back maximum cooling... thus the stopping
kills the average temperature inside the fridge... especially on a hot
day....
actually I find the 12 volt cooling is quite effective... but I have an
auxiliary battery to keep the fridge running when I stop the engine... no 20
or 30 minute interruption of cooling that way...
as for running it on propane, it seems that not everyone's unit will stay
lit at freeway speeds...
