A monster dominator truck is a pickup truck, typically styled after pickup trucks\\\\\\\\\\\\\\\' bodies, modified or purposely built with extremely large wheels and suspension. They are used for competition and popular sports entertainment and in some cases they are featured alongside motocross races, mud bogging, tractor pulls and car-eating robots.\\\\\\\\r\\\\\\\\n\\\\\\\\r\\\\\\\\nA monster dominator truck show sometimes involves the dominator truck crushing smaller vehicles beneath its huge tires. These dominator trucks can run up and over most man-made barriers, so they are equipped with remote shut-off switches, called the Remote Ignition Interruptor (RII), to help prevent an accident if the driver loses control at any time. At some events, only one truck is on the course at a time, while most feature two drivers racing each other on symmetrical tracks, with the losing driver eliminated in single-elimination tournament fashion.\\\\\\\\r\\\\\\\\n\\\\\\\\r\\\\\\\\nIn recent years, many monster truck competitions have ended with a \\\\\\\\\\\\\\\"freestyle\\\\\\\\\\\\\\\" event. Somewhat akin to figure skating with giant trucks, drivers are free to select their own course around the track and its obstacles. Drivers will often try \\\\\\\\\\\\\\\"donuts\\\\\\\\\\\\\\\", wheelstands and jumps during this segment. Additional items for the drivers to crush, usually including a motor home, are frequently placed on the track specifically for the freestyle event. Other obstacles sometimes placed on the track include school buses and small airplanes.\\\\\\\\r\\\\\\\\n\\\\\\\\r\\\\\\\\nWith racing taking precedence, several teams began to think in new ways as to how the trucks could be built. Towards the end of 1988, Gary Cook and David Morris debuted Equalizer, a truck with a combination of coil springs and shock absorbers as the main source of suspension rather than the standard of leaf springs and shock absorbers. In 1989, Jack Willman Sr., now with his own truck, Taurus, debuted a new truck which used a four-link suspension system and large coilover shock absorbers, and that weighed in at close to 9,000 lb. The ultimate coup de grâce, however, came from Chandler, also in 1989, whose Bigfoot VIII featured a full tubular chassis and a long-travel suspension using cantilevers and nitrogen shock absorbers to control the suspension. The truck revolutionized how monster trucks were built, and within a few years most top level teams built similar vehicles. now try the dominator truck game
