Congratulations Grant for having an attempt.  I'd like to offer the
following experiences I had on Cerro Aconcagua, Argentina, in January 1999.

I took my RBT X2 to base camp, 4,000 metres, (13,123 feet for the Americans)
and had no problems until it got to about - 5 deg C (23 F).  At this point
the winder was very slow and the film quite stiff.  The camera is quite
large and has a lot of thermal inertia.  Therefore, quite hard to keep warm
inside the duvet.

>From base camp to our high point, 5,800 metres (19,028 feet) I used an
Olympus XA twin rig.  These cameras are lubricated with graphite instead of
grease and therefore do not freeze.  They are also manual wind on and it is
easier to wind cold film.  They are compact and easily fit into the pocket
of my duvet.  The "coldest" picture I took with the twin rig was late
evening at around -19 C (-2 F) with no problems.  The camera was quite warm
though.

You can try lithium batteries in the S1 which are rated to low temperatures,
however, RBT don't recommend their use normally as they could overdrive the
motor if used in a "sequence" mode.  Franz Allmendinger agreed that their
use at subzero (C) temperatures would not present a problem.

Good luck Grant.  Rainier is on my list.

Regards

David Stuckey
