Mark Martin's retirement has no golf course included, just a Newell, his toolbox, and a few good friends. Ever Mark retired it has been pretty well known that he is a HUGE motorhome/rv guy. Mark loves his Newell Coach rigs and has one of these 45 foot long beasts custom built about every 3 years. Part of his process is taking it out to the guys at PDI in Utah for a crazy compound turbo setup and custom dyno tuning on the factory equipped Cummins X15 and Allison Transmission powerhouse. Mark often pushes the limits of what the manufacturers intended on doing with specific parts sometimes even making his own in an attempt to improve on something (or sometimes make it worse as he explains). We get the technical details straight from Jerad Whitwer (the owner of PDI) who happened to be at the Las Vegas race with Mark when we were there to film him driving JR51 before the race!
