4x4 Top Truck Challenge: Join us as we hit the dirt with locals from across the island of Oahu. These amazing trucks, jeeps and off road vehicles bring you into the outdoors where rock crawling and mudding abound. This segment will send your laundry-loving, Downy-worshiping mother to the mental institution. We take you through the wringer through lots of mud and oversize tires to Oahu?s Top Truck Challenge at Kualoa Ranch. Watch our 4x4 maniacs destroy their vehicles. Monster trucks trample Chevy Novas, souped-up 4x4?s bounce over boulders Iike toy Tonka trucks and Go-Carts spin their wheels through mud bogs and come out looking like chocolate-dipped pretzels. Its an exciting day of heavy and extreme four wheel drive competition.
