It’s been a little while since you’ve heard from Hennessey’s astounding Hellephant-swapped RAM TRX, and for good reason! The truck has been under the knife to become the first 1200 HP MAMMOTH 6x6s. This Hellephant-powered production run is limited to three examples and all are spoken for, but Hennessey is now proud to offer 6×6 conversions for the still-ridiculous MAMMOTH 1000. In this video, some of the team behind this outrageous build hit the road with their masterpiece for a bit of driveability testing.
