The RV Rampage tour hits the road before dawn from Wellington to catch an early morning ferry to New Zealand's South Island. In Marlborough, the biggest and most famous area of wine production in New Zealand, the Tourist Challenge is competitive wine tasting and identifying grape varieties at the Yealand Vineyard. But it's not all quaffing fine wines; Henry and Amanda are putting the teams to work on the vines with the backbreaking task of "bud rubbing". Day Two in the South Island and the teams make the long drive to the Abel Tasman National Park, where they are heading for their Rampage Challenge, a gruelling sea kayaking course crossing the ocean to an island were they must locate RV rampage flags. It's not long until exhaustion and stress takes one team beyond breaking point.
