That thread was more about the drivers than the actual trucks and which driver was being more of a dick than the other. And like you said, the comments were borderline argumentative. That's the only reason I can see why even it got posts on a GM passenger car forum.
Your thread on the other hand has nothing confusing or controversial about. Just a clean win over two Dodges. I watched it when you first posted this, but I just don't know anything about diesel Fords or Dodges like a lot of guys on here so I didn't have any constructive input.
Anyway, you know how people (including myself) tend to flock to controversy no matter what the topic is. But under any other circumstance, threads about diesel trucks usually just aren't that popular on this forum.
