In the final challenge, the teams convert their vehicles to travel across Colorado River, but that's only the beginning. To win the race, the score leading team members must also drive the vehicle to Vegas, and cross the finish line at the Flamingo hotel. At race day, Farm Boys passed the river first, followed by Metal Maidens and Fire Power. Anarchy's vehicle stuck at river bottom, and was forced to quit. At the second half the trip, the surviving teams retained their ranks. Final scores Anarchy: 0 points (4 total) Farm Boys: 4 points (10 total) Fire Power: 2 points (2 total) Metal Maidens: 3 points (9 total)
