When the final four teams hit the streets of St. Louis, Tyler is there to give them a challenge illustrating how a premium product is as good as money in bank. The next morning, Tyler gives them a truck stop challenge with the ultimate prize -- the winning team will see their week's till doubled. Emotions are high at elimination as only three teams will get to head southward on the next leg of the Great Food Truck Race.

Tyler lays down the final gauntlet, as the teams must revisit each of the six lessons learned throughout the race, on an epic Florida road trip. They finalize their menu in Tampa, create a radio spot on the beach, partner up in Naples, take airboats into the Everglades for fresh alligator and then battle head to head in a cooking challenge to double their till, all before arriving in Key West. The teams sell on Duvall Street before being called to the White Street Pier for the final tally announcement, where one team will be crowned the winner of the Great Food Truck Race, driving away with $50,000 and the keys to their very own food truck.
