Everybody’s told them it can’t be done but Jase and Simon are determined to tackle one of the steepest and toughest tracks in Far North Queensland. They’re trying to find a wrecked World War Two American fighter plane but getting there is going to test them and their gear to the limit. As soon as they set off they find themselves in trouble. Will their very own ‘Big Bang Theory’ get them back on the track or will they be forced to call it quits? This could be their most challenging trip yet and when both trucks break it will take knowledge, experience and a fair dose of luck to keep going. It’s a DIFF-icult start to a trip that already promised to be one of their toughest.
