For the Dieselsellerz giveaway, Thunder vs. Lightning, two lifted F450s compete and the winner decides which one to take home; the guys continue turning a busted '69 Chevy C10 into a diesel low rider for a millionaire client.

The guys face a huge challenge when a big dollar collector asks them to slam a 1969 Chevy C10. Meanwhile, Heavy D and the guys are off to bike week at Sturgis, to check out a one-of-a-kind hydrostatic diesel motorcycle.

When the local Sheriff asks for a new search and rescue vehicle the team are excited to build an amphibious Sisu Nasu. Moreover, the diesel Brothers team makes every effort to impress with their next work truck giveaway. A Dodge 5500 with all the bells and whistles.
