The Flattest Place on Earth

Taking a break from the high-mountain passes, Lisa and G.W. take a load of live animals over the world's largest salt flat, where they'll have to rely on a faulty GPS and a bit of luck to find their way across one of the flattest places on Earth. Tim and Tino take on the death road, and Tim's out for a new, high-adrenaline experience, finding there's plenty of room to ride on the roof of the truck. Hugh's gone about just as far as he can, too, finally learning that you can't deliver your load any faster if you don't keep your truck on the road.
