- "Is it an SUV? Is it a muscle car? Is it serious military hardware for the oligarch market? It's all of the above with six wheels and a bulletproof shell (if you pay for the extras). No dictator or business leader should be seen without it."
- ―Warstock Cache & Carry description.
The Dubsta 6x6 closely resembles the 6x6 variant of the Mercedes-Benz G63. The vehicle may also draw some inspirations from the Mercedes-Benz G Class models modified by the aftermarket tuning company Brabus.
In contrast to the stock Dubsta, the 6x6 comes equipped with a large skid plate at the front. The stock wheel design for the 6x6 also differs from that of the standard Dubsta.
Just like the G63 6x6, the Dubsta 6x6 has a truck bed along with an extended chassis to accommodate the extra rear axle. Like the real-life counterpart, the Dubsta 6x6 comes with load bed roll bars as standard (albeit a smaller group). The truck also has a higher ground clearance to make way for the bigger off-road purpose tyres.
As expected from a large 6-wheeled truck, the Dubsta 6x6 is exceptionally heavy, however it is a very stable vehicle. It is powered by a large V12 engine coupled to a 6-speed transmission, which is capable of powering the vehicle up steep slopes with relative ease. Its top speed and acceleration are quite impressive (being superior to all Off-Road classed vehicles), but handling leaves much to be desired, as it has a large turning radius due to its long wheelbase. Braking is also sub par, with upgrades doing little to improve it. Durability is excellent, as it is able to withstand many head-on collisions before the engine fails. The 6x6 can easily push smaller cars off the road and it can withstand large amounts of gunfire. Bulletproof tires are highly recommended as for its handling not be hindered by gunfire from its large, exposed tires.

- As a direct variant of the original Dubsta, they share most of the accessories at Los Santos Customs. The only omissions is its rear spare tire, side steps, snorkel option and exhaust modifications.
- It shares the rim design with the Merryweather Mesa and the Sandking XL.
- The Dubsta 6x6 is one of two civilian vehicles (aside from industrial trucks) in the series to have six wheels in total, the other being the Splitz-6 ATV.
- A minor visual glitch is present on the Dubsta 6x6. If players riding in the bed aim their gun or turn their torsos a certain way, their bodies will clip through the rollbars as if they weren't there.
- Despite being roughly the same size of a Sandking, it can be washed at car washes throughout the city.
- The Dubsta 6x6 has similarities to the Bravado Bison, in that players may ride in the cargo area of the vehicle. The only difference between the two is the Bison's lack of bodywork modifications.

Its the only Offroad vehicle in the game that features it's very own unique vehicle display.
