Oz and James's Big Wine Adventure

Arriving at the glamorous Napa Valley, they are dismayed to discover that they're staying in the car park. The pair argue about who will empty the RV's waste tank, then sample Californian champagne at the Tattinger estate. Next, the Schramsberg estate, where the quarreling continues with a heated debate about what bubbles taste like. Frustrated, James rents a Mustang Shelby to get them out of the hated RV.
