The Dumper is by far the largest land-based vehicle in GTA San Andreas, generally based on large off-road dump trucks used in large-scale earth moving; the truck resembles a cross between a 1970s Caterpillar 773 (particularly the grille and cab) and more modern 773s. The Dumper is also only available in one color: Bluish gray, similar to the Dozer.
- The default radio station in the vehicle is K-Rose.
- The Dumper, along with the Monster, has the car crusher ability which allows the vehicle to be able to drive over traffic, rather than through it.
- If a car hits the back of the Dumper, it will be set on fire or badly damaged. However, if the vehicle is directly on top of a car, sometimes the Dumper will get stuck on top of the car. The car will eventually explode and the Dumper will also explode too.
- The Dumper is the biggest land vehicle in Grand Theft Auto: San Andreas, and the Monster is the 2nd biggest.
Along with the Dozer, the Dumper is integral to quarry side-missions in Hunter Quarry, Bone County, and is also made available during "Explosive Situation". Upon completion of all quarry side-missions, a Dumper will spawn outside the quarry grounds. You can also do the Quarry mission and when you use the Dumper, you can steal it. Also, on certain occasions, the Dumper will spawn in the Underground Parking Garage at the Las Venturas Police Headquarters in Las Venturas.
