Stacey David did a bit on the Gama Goat as part of his show, Gearz on SPEED. The Gama Goat is a military transport vehicle that was built during the Vietnam war. It answered a demand for a vehicle capable of traversing rough terrain that was hanging up the classic Deuce and a Half 2.5 ton truck. The Gama Goat is a 6×6 with an articulating body, independent suspension and lockers on all three axles. Power is provided by a Detroit Diesel supercharged, 2-stroke, 3 cylinder engine. The body was made from aluminum which allowed the Gama Goat to float. Unfortunately, not too many were made due to high cost and complexity, but they definitely got the job done off-road.
