Individual Challenge: Starting out on a boat, each contestant was given a large tank filled with 250 pounds of slime eels.
Individual Challenge: In heats of two, contestants drove a bulldozer through a slalom course, pushing a tire as they weaved around obstacles.
The contestant who completed the course and returned to the starting line with the fastest time would win an advantage in the next individual competition.
The pairs selected for the challenge were Scott & Sarah, Swifty & Merryl, Celi & Liz, Iraida & Cyril, and Angel & Patrick.
Individual Challenge: Rappelling down the side of a four-story building, contestants had to work in teams of two and alternate between washing windows while suspended in the air and holding the rope for their partner at street level.
The pairs chosen for this challenge were: Scott & Merryl, Cyril & Liz, Iraida & Patrick, and Sarah & Swifty.
Team Challenge: Teams had to search a car recycling plant for replacement parts to a car: a front bumpers, headlights, a hood, two front doors, a sliding door, taillights, a rear bumper, four wheels, four seats, and a battery.
Overtime Challenge: Contestants had to remove the fly wheel, the exhaust manifold, and the oil pan from an engine.
Overtime Challenge: Contestants had to install a series of pipes so that the water from a shower, sink, and toilet could flow into a bucket.
Individual Challenge: Contestants were paired up into teams of two and had to signal a crane operator to move six metal beams to an iron structure.
The first pair to bolt in the beams and attach a Christmas tree and an American flag on the top would advance to the final challenge.
Final Challenge: Contestants had to race through a series of obstacles based on previous challenges on the season, having to break through a wall with a sledgehammer, use a jackhammer to release a bolt cutter from a concrete block, cut through a chainlink fence, stack ten lobster traps to climb to the top of a shipping container, saw through a chain to drop an I-beam and cross a gap, and untangle two marine lines to pull up a ladder in order to reach the Ford truck at the finish line.
As the winner of the final challenge, Scott became the Tough as Nails Champion, winning the $200,000 individual prize and a Ford Super Duty truck.
