Oxygen Required

All three trucking teams get a little entertainment in on the side when truckers Tim Zickuhr and G.W. Boles show what they've got in a Bolivian Cholita Wrestling ring. Back on the road, it's the team's last chance to prove they have what it takes to conquer the death road before moving on to Peru. Lisa again relegates G.W. to the spotter's role, still hesitant to let him take the wheel. As Tino and Tim climb higher and higher into the mountains, their emergency tank of oxygen comes in handy. Hugh struggles with the altitude and attitude trying to get his truck through tight squeezes and narrow roads. Finally, all the drivers meet up for dinner and recount their weeks on Bolivia's Death Road.
