The remaining six teams arrive at the Naval Air Station Pensacola in Florida to receive their next marching orders. For this challenge, the highest grossing teams from the first leg of the race get to pick teams to work with to feed 50 service members. The teams pair up and have one hour to cook before the hungry service members arrive. The teams with the favorite dish get $200 added to their final till. Next, they hit the streets of Pensacola to sell their dishes. But the teams get a chance at a life vest when Tyler offers immunity to the next round to the team that can make the most profits off a dish featuring the special of the day, a full fresh Red Snapper.
In Santa Fe, N.M., Tyler Florence challenges the five teams to use peppers to create the ultimate spicy Sante Fe meal. The hot challenge comes with a hot $1,000 prize.

With just a few miles before they reach the small art community of Santa Fe, N.M., the six remaining teams make frantic calls to local tastemakers to rally support for their weekend of sales. After meeting Tyler in Santa Fe Square, they receive a stipend and the action begins. The teams are interrupted as Tyler calls with their Truck Stop challenge: the teams must each add a special dish to their menu that includes local red or green chiles. Over the weekend, secret judge Eric DiStefano (Coyote Café) samples each of the dishes, and the winning truck receives immunity from the weekend’s elimination.
The seven remaining teams roll into Salt Lake City, and Tyler immediately explains the Truck Stop challenge: the teams must create an original sausage dish with the ingredients on the farmer's table, but the sausage is missing. The trucks head to world renowned Creminelli Fine Meats and create three customized links of sausage in hopes to impress guest judge chef Ryan Lowder and add $200 towards their final tally. The Speed Bump adds another game-changing twist as Tyler calls the teams and tells them to move the trucks to a new location, no matter how many patrons are on line.
The final two teams arrive in Miami to a breathtaking view of this iconic city and receive their final challenge — each team must make $15,000 dollars and then race to the finish line in South Beach, and the winner gets the $100,000 grand prize.

Then, the teams are rocked with a second Speed Bump - their current locations are shut down and they must head to the Cuban enclave of Little Havana. On day three, the finalists meet Tyler at the Miami River for the long awaited Truck Stop challenge: the teams will create a delicious seafood dish for local chef Michael Schwartz, but they must head out on fishing boats in the Atlantic Ocean to catch the fish on their own. As the trucks close in on the grand prize, it's time for the final Speed Bump - the teams must shut down and become a dessert truck for two hours on the final day.
Tyler and "Good Morning America" anchor Robin Roberts meet the six remaining trucks at a ranch outside of Denver.

The four remaining teams pan for gold to earn their seed money, and some teams gain a clear head start on shopping and selling. Meanwhile, extreme cold and winds continue to challenge everyone.

The trucks roll into the Old West town of Yuma, Ariz., and head to the historic Yuma Territorial Prison, which used to house prisoners from all over the Wild West. Tyler Florence gives the teams a relay challenge involving artichokes and bacon, and then they must add an original dish starring those ingredients to their menu and start selling. The residents of Yuma show up in full force, with lines 20 people deep waiting to try the trucks' specialties. After a day of massive sales, one team is eliminated, and the final three trucks head to the next destination.
Tyler Florence welcomes the teams to Las Vegas and gives them a challenge using one of the most popular items on Vegas menus: shrimp.

Then, Tyler and Las Vegas restaurateur Elizabeth Blau visit the teams to offer business and culinary advice, and the teams sell their signature dishes on the streets of Vegas, with the least successful truck being eliminated.
Four teams remain as they enter the Twin Cities — Minneapolis and St. Paul. In honor of the Twin Cities, Tyler gives the teams twin Truck Stops.

The first team to make $500 and meet Tyler at the Peace Officers Memorial at the State Capitol building wins a huge reward, and with only four teams left, this reward could save a team from elimination and send them on to the next city.
