It's How You Get There

Greg gets a 557-horsepower Rocky Ridge Alpine-edition Silverado and Julian gets a 435-horsepower Jeep Wrangler before they head to Richard Petty's personal farm to race the newly acquired vehicles in the mud.

The boys are joined in West Virginia by Jenn Barlow as they run a timed race in a Porsche SUV on Snowshoe Mountain, tear through the woods of Bear Wallow Trailhead in Mahindra UTVs, and ride to New River Gorge on two Harley-Davidson motorcycles.

Greg, Julian and Jenn take on the Top of the World Trail in Moab, Utah, where they test the mettle of three rock-ready Jeep Rubicons and try not to get stuck on the way to the top.

Greg takes Julian out on Lake Michigan in an extremely versatile boat with a big, road-ready surprise; Julian is introduced to the RV lifestyle; Julian and Greg circuit race two jacked-up go-carts and drag race two high-powered riding mowers.

Greg and Julian head to Chuckwalla Valley Raceway in Desert City, Calif.; they test out two motorcycles, a Ducati 959 Panigale and a Suzuki GSXR-1000, then they switch to a 2016 Dodge Viper ACR and a Challenger Hellcat SRT.
