The Diesel Brothers are back! Diesel Dave picks his first giveaway truck and dreams big attempting to build the 2020 version of the Kodiak. Todd LeDuc challenges the guys to a desert race and flips the script by picking The Muscle to be on his team.

Diesel Dave continues work on his epic modern-day Kodiak while making sure he doesn't break the bank. Sam the Mad Scientist then unveils "The Kraken" -- a diesel-powered monowheel vehicle that is unlike anything the guys have ever seen.

Mad Scientist Sam's wild creation, The Kraken, comes to life but Heavy D continues to be skeptical of the build's potential viral success. A high profile client wants to customize a Ram 3500, which puts Diesel Dave and The Muscle to the test.
