The trucks travel to Phoenix and meet Tyler 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 full day's sales in Phoenix is a close one, with the top four teams totals separated by less than $60. At Rawhide Ranch, the truck that made the least money is named and the four remaining teams move forward.
