I believe this is one of a bunch of Tuckers equipped for, and used in, exceptionally cold temperatures on the North Slope of Alaska. The "Fat Cat" cab has insulation for the extreme temps.
A fellow in Alberta had a bunch for sale and though they all are high hour machines, supposedly they have been through his shop and repairs, overhauls and servicing has all been done as needed. Also, while the hours are high supposedly a considerable amount of the hours on the meter(s) were with the engine(s) idling.
They've been listed for sale on several websites and I believe a purchaser has the option of either the Tundra Tracks currently on the machine or Terra Tracks. As I recall, the prices were surprisingly low when considered against what the machines likely cost new.
But I think they are VERY heavy, and thus not well suited for recreational use in deep snow conditions...just my opinion.
