questions re camping at altitude with norcold refrigerator

Whatever works best for the individual. The monster 400-amp Niehoff on the bus kept the 8 L-16's happy which kept the Trace 812SB fed.

But regardless -

A talented propane man can tweak the flame of your Norcold to immediately light off at extreme altitude. Carry tools to change orifices. At 11K feet I stored refrigerated stuff in an Igloo ice chest in an outside storage bin. Worked like a charm.
