We love attending the Ultimate Callout Challenge for a number of reasons, but getting to speak with competitors and racers excited for the weekend is one of the best parts. It’s even sweeter when we get a chance to speak to someone like Zachary Fish, who was a first time ODSS racer during the UCC event. We spoke to Zach about his truck and its 5.9L Cummins engine. It’s our Diesel of the Week brought to you by AMSOIL INC.
