LIMITED EDITION

MAMMOTH 6X6

The Hennessey MAMMOTH 6X6 is the ultimate Ram TRX in the most American way possible: bigger, longer, taller, more power, more noise and plenty more of everything! Hennessey has significantly extended the TRX platform and added a third axle and a gigantic flatbed at the rear.
