Guy Fieri gives food truck families the ultimate road test by challenging them to shop, cook and present their dishes together as a team. First, they must make their truck's best seller while taking a tag-team shop, where each family member shops in 60-second sprints as part of a four-minute grocery relay race. Then, the remaining two teams make their personal food truck favorite while also incorporating a dish style and condiment determined by two spinning food truck wheels. The winning food truck family will roll out of Flavortown with up to $20,000.
