The Great Food Truck Race (2010)

Season 7: Episode 4

The final three teams brave the sweltering desert heat of Palm Springs, Calif. as they take on a challenge that tasks them with making something sweet to eat. The next day, they must become "human roadside attractions" and create a costume to draw customers to their truck. For one family, tempers flare as temperatures rise, and in the end, another team goes home while the last two family food trucks set course for the finale.
