1994 Norcold Tek II Refrigerator noise and current draw

Buying any refrigerator that has less than 2" of closed cell insulation is like fruitless. Noise can be controlled with texture foam and baffles in ventilation. Please remember it isn't merely how much current the unit draws but the daily on cycle time. My Vestfrost units are not particularly stingy when running but they do not run often.

This is why an "apartment size" refrigerator uses as much power as a well insulated 14 CF refrigerator. They run 24/7 except in Moosemate, Yukon, Christmas Eve.

old 90's model with AC voltage compressor or late model with DC compressor ?

i don't know about noise ?
the similar one i had in an Dodge camper van was quiet
but it was a real battery sucker
IIRC correctly it uses an AC voltage driven compressor and has its own built in inverter to turn DC to AC for the compressor

i think i would pass and not buy it, well maybe if it was super cheap, like less than $100
but not for $300-$400

if your looking for efficient DC power fridge, there are newer better options out there
BUT if this a late model with a Dan Foss style DC compressor, then yeah go for it
