Earlier this week I featured a 2004 Unimog U500 that was the ultimate motorsports support vehicle. Today another 2004 U500 is on the auction block that can perhaps be the ultimate utilitarian workhorse. The OM906LA diesel motor inside this truck makes 811 ft/lbs of torque that, like I said earlier, is enough torque to pull a house off its foundation. But this U500 located in Colorado offers much more than just a bunch of torque and 395(!) series tires.
