In this special episode, Jeremy Clarkson, Richard Hammond and James May are forced to go on an RV holiday in the southwestern United States, despite regarding such things as slow, uncomfortable and pointless. Pushed to breaking point within 24 hours, the hosts decide to take matters into their own hands by each buying a used RV which they can then modify to suit their own personal preferences before continuing their vacation across Nevada in comfort, or a near approximation of it.
