After Angela accepts a job from Dave, Big Donny lures her away with a better offer; Dave tries to get back at him by buying a truck Donny wanted just so he can flip it to him for a profit; an overworked Junior convinces Craig to go for a joyride.

Dale takes on river crossings and rocky mountain roads while hauling a piano by himself to a wealthy client with sky-high expectations; the engine in Dave's brand-new hotshot truck fails, leaving him a narrow window to replace it before the deadline.
