Overview: Can you believe in over 130 episodes the Dirt-Heads have never built the iconic Chevy K5 Blazer? These trucks were super prolific and are now becoming collectible. So much so that Fred and Dave bought a real stinker of an icon. But the guys have a great plan: winch it on a trailer, and start heading to the desert for some four-wheeling, with multiple stops along the way to get it running and modified for better off-road performance. The plan seems simple in concept, but with the Dirt-Heads it's never as simple as it seems.
