The trucks travel to Phoenix and meet Tyler Florence at a Sonic Drive-In for a blind taste test and original savory dish challenge inspired by Sonic's signature drinks. One team member is left operating his truck solo when his teammates leave the race, and the day's sales in Phoenix are close, with the top four teams separated by less than $60. At Rawhide Ranch, the truck that made the least money is sent home, and the four remaining teams move forward.
