Synopsis

The question of America's toughest truck is put to the ultimate test as Tanner, Rutledge, and Adam venture into the mountains, subjecting their vehicles to seemingly insurmountable challenges. Beyond that, Tanner explores the Louisiana swamps with a novel off-road machine, engaging in a high-stakes race against an airboat. And adding his signature wit to the proceedings, comedian Bill Engvall makes an appearance at the Top Gear test track.
