The final four trucks head to the heart of the South in Nashville. For their Truck Stop Challenge, the teams have to create a down-home country style picnic for country music stars Joey & Rory. The competition shakes up when Tyler reveals the next Speed Bump: to simulate what happens when employees don't show up or call in sick, Tyler tells the teams that two members must sit out and they must train two students from the Art Institutes Culinary School to work on the truck.
