I have to chime in here.. the VIN on the truck in question tells me:
The truck is a 2007 model year, built in the Denton factory.
(I know, I always have to put a Peterbilt spin on everything..)

#5 The first number is the "Vehicle Identification Number".
The second number is the "Inter-Continental-Carrier" registration number.
The third number is "United States Department Of Transportation" registry number.
The fourth number is the "Gross Vehicle Weight" rating number, showing how much total weight is allowed to be carried (usually this number is 80,000LBS, but since this carrier uses split tandem trailers, they have an extra 10,000LBS extra allowable weight difference).
The fifth number is "Gross Vehicle Weight" rating in metric weights (this carrier runs in and around Canada a lot).
#6 See #5 for U.S.D.O.T.
I hope this helps you out....
