How does the Cummins Diesel Jeep Wrangler “Tubesock” compare to a gas-powered Jeep? On this episode of Dirt Every Day Fred Williams and guest host Cummins Steve transform Tubesock from a diesel-powered submarine Jeep to a trail and street Jeep, and then take it head-to-head against gas inline-six and V-8-powered Jeeps on both highway and dirt. How does the little four-cylinder diesel stack up against the tried-and-true gas-powered trail machines? And can Cummins Steve convince Fred and the viewers that they want a Cummins under the hood of their next off-road project truck? Watch now!
