Hennessey Introduces $20k Overlanding Kit For Ram TRX-Based Mammoth 1000

Most off-roading is usually done at a leisurely pace, but Hennessey wants to put an end to that with the introduction of a new overlanding upgrade for the Mammoth 1000 TRX.

Overlanding is a specialized form of off-roading. Instead of completing a set off-road trail with several obstacles and escape routes or simply hooning around in the mud, overlanding is an extended journey into the wilderness. You have to be entirely self-sufficient, and most of the accessories you need are mounted to or contained within the vehicle.

That's precisely what Hennessey focused on with the Overland Edition, which retails for $19,950 (not including the truck, obviously.)


All of the additional equipment is fitted to the Ram TRX bed. Since Hennessey doesn't make any upgrades to the bed to build the Mammoth 900 or Mammoth 1000, it's theoretically possible to add this to a standard TRX as well.

Either way, a robust bed rack serves as the foundation. On top of that, Hennessey mounts a hard-shell rooftop tent that can be erected in minutes. A retractable 55-inch awning is also included. That's sleeping space and shelter sorted. An auxiliary fuel tank and pressurized water reservoir take care of gas and clean water. Food is, unfortunately, your responsibility.

Other accessories include a 28-inch splitting axe, a shovel, LED perimeter lights, grab handles, and a retractable ladder for easy access to the tent.


These features are bolted to the bed of the Mammoth 1000 TRX, which has an upgraded supercharged V8 producing 1,012 horsepower and 969 lb-ft of torque. If you want to slow down and enjoy the scenery, might we suggest the Mammoth 900 instead? Its supercharged V8 only produces 912 hp and 873 lb-ft.

Hennessey also mentions that most overlanding customers opt for the Stage 2 Off-Road Enhancement Package. It adds sturdier custom bumpers, LED lights, a front leveling kit, 37-inch off-road tires, upgraded electronic fold-out steps, and a three-year/36,000-mile warranty.
