Mike Graves says the Ultimate Callout Challenge 2017 will be an amazing event for the diesel industry. Mike's Hollyrock Customs will be participating, for sure - but he also hopes to actually watch the anticipated power in action. Some of the horsepower numbers tossed around go as high as 3,500. Mike says his build will not go that high. He's mostly worried about one event - the sled pull. His truck has never seen "the dirt".

It's always great to hear from Mike Graves of Hollyrock Customs.
