Well Glyn: My very own personal oxygen depletor cuts in at 8000' so the
heck with the heater - it's on its own. Probably the highest I've had
my Bubble was while under tow, so to answer your question, the highest
I've operated the heater was may a couple hundred feet. Have you heard
from the Force 10 people yet? I called them about the knob and they
were NO help, no interest, nada.
