We hit the interstate in southern Utah to see how the most powerful 2027 Newell P50 handles the road. Once we get back to the shop, Mark takes us inside his custom storage bays for an exclusive, deep-dive toolbox tour. He breaks down everything he has learned over an 11-year span on the road—sharing his exact organization secrets, custom storage hacks, and the essential tools he always keeps on standby. If you love high-end diesel performance and elite tool organization, this is the ultimate rig tour from a legendary NASCAR driver.
