2000 W900L - straight-piped C15 (6NZ)13-speed

Excuse the rough shifting. I drove this truck much, much better when I didn't have the differential lock engaged. I was out in a muddy field for such a long period of time, waiting on other trucks to get loaded and unstuck that it totally slipped my mind to flip the lock back off when I finally got back to solid pavement. I realized my mistake and corrected the issue, shortly after ending the video. Just a few minute portion of a run from one of the smaller corn circles, back to the dairy. Typical load that grossed about 100,000 lbs. To avoid monotony, I cut the video before I shifted into the big hole and grabbed the last two gears because the truck's got pretty tall gearing. It'll tach 1,300 RPM @ 65 in high gear.
