M818 Tractor Truck

The M818 Tractor trucks are based on the 5 ton 6x6 M809 series truck. They were used to tow Semi Trailers up to 37,500 lb (17,000 kg) with 15,000 lb (6,800 kg) on their fifth wheel. Thhe Semi-tractor/trailers had to stay on relatively flat ground, and are not rated for full off-road use. On improved roads they could tow up to 55,000 lb (25,000 kg) with 25,000 lb (11,000 kg) on their fifth wheel.  The M818 normally towed a 12-ton 2 axle trailer. There were stake and platform, van, low-bed, and tanker bodies.
