Overview: The final two teams head back to Los Angeles, where their trucks have a ferry to catch to Catalina Island. First, however, the teams must become hot dog vendors in the port town of San Pedro, Calif. to compete for a distinct advantage. Once on the island, it's a head-to-head family face-off as the final two teams sell side-by-side, putting everything on the line before finding out who will get $50,000 and be crowned winner of The Great Food Truck Race.
