context_page_description: The M809 Series 5-ton 6x6 truck was a family of heavy tactical trucks built for the United States Armed Forces. The basic cargo version was designed to transport a 5-ton, 14 ft long load over all terrain in all weather. In on-road service the load weight was doubled. Built by AM General, they evolved into the M939 Series.
context_section_description: M818 Tractor trucks 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. Semi-tractor/trailers have 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. 6-ton 2 axle expansible vans and 6-ton single axle vans were also used.
