Kristi was commercially built in Colorado. The original Kristi company offered 3 basic models. The models were the KT2, KT3 and KT4. Total production of all the units combined, over the entire 12 year life of the original company's lifespan was lower than 1 year of production of commercially viable snowcats from Tucker Sno-Cat, Bombardier or Thiokol all of which were produced in North America during the same time period. The company changed ownership and moved to Washington and continued production. Production was always on a small scale, and the products were innovative. The most refined of the Kristi snowcats was the KT7, which was last produced and the least successful commercially with only 4 units built and 3 of them were prototypes that failed. The KT7 was designed and produced after the sale of the company and after it moved to Washington. It is possible that additional KT2, KT3 and KT4 units were manufactured by the new owners in Washington state but it is unlikely since the designs had not been substantially upgraded by the time the new owners purchased the company. A slightly smaller version of the KT3 was called the KT2. Both the KT2 and KT3 were powered by Volkswagen air-cooled 4-cylinder engines, it is reported that a small percentage may have been powered by Porsche engines. The KT2 and KT3 shared mechanicals and even shared the same operators manual. The VW engine developed 32 horsepower.
