Roger Mooking is on the hunt for the most radical barbecue rigs, and he starts at The Pit Room in Houston, Texas, where special events call for a custom-built trailer that can cook up to 600 pounds of meat. Roger helps load up six whole goats for tacos. In Napa Valley, Calif., he checks out Oak Avenue Catering's custom-made asado grill that can cook a huge side of beef. For a side dish, fermented cabbages are hung on the grill to cook low and slow with the meat. As they wait for this feast to cook, Roger learns how to transfer a tree stump into a flaming stove for boiling potatoes that are then crisped on a hot plancha to complete this feast in the heart of wine country.
