How well do the Mr. Heaters work at altitude?  The FAQ on their website
states:

"The Portable Buddy uses an Oxygen Depletion System (ODS) which is a safety
device used to light the heater as well as shut it off if Oxygen levels drop
to between 18% and 19%. The Buddy should operate without any problems up to
7000 FT above sea level. At higher altitudes, the ODS may cut-off
prematurely resulting in what we call a nuisance shut-off. What happens is
the molecular structure of the air at higher altitudes may cause the
air-flow in the pilot to increase and blow the pilot flame off the
thermocouple, causing the heater to automatically shut-off. Also, if you
have a change in weather and the barometric pressure drops, this could also
cause the heater to shut down prematurely."

Just wondering,
