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. As with all other heavy machinery, it is part of the DUDE company. The Dumper is also only available in one color: Bluish gray, similar to the Dozer.
The Dumper is a slow moving vehicle (with a top speed roughly similar to that of a Linerunner), but has the effects of the Rhino tank. The "tipper" on the back can be raised up and down, and due to the size of the wheels, it can replace even a Monster Truck.
- The default radio station in the vehicle is K-Rose.
- The Dumper, along with the monster have the car crusher ability which allows the two vehicles 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.
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.
