The M-29 Cargo Carrier, developed for the United States Army by
Studebaker in 1942-1943, also known as "The Weasel", is a
lightweight cargo carrier weighing 3,800 total pounds.
With a ground pressure of less than two pounds per square inch the
Weasel would float across snow. It was used by the Army to transport
both cargo and ski soldiers, at a maximum speed of 36 miles per hour.
