Santa left me a Coleman sportcat heater, the basic 1500btu
model. :-)  Anyone use these while vanagon camping and care to share
tips?   How long does it take to heat up a cold van in the morning?
What sort of temperature differential can they handle before you
drown in humidity or die of CO poisoning?   Would it be possible to
mount one of these near the stove or fridge, and tie it into the
van's LP system?  Might make a really cheap alternative to a built-in
heater?
