I have not seen or heard what the actual dimension behind centerline is but my money is on MORE than 2".

If they do this on the longbed trucks they really are boneheads.

Makes no difference though. We already KNOW what the result is due to the CAT scale tickets.
100#, so do some backward computations until you arrive at a method that matches the result.
That will be the correct method.

As an aside, banter on GM forums is that this move was only for the SB/CC models.
It kind of makes sense, as that configuration could benefit from such a change.




I have no idea where their mistake is but if the cat scale is right and the 2" is right then maybe they filled the truck with fuel after getting an empty weight and before getting their gross weight.


How about how many passengers were aboard the truck during the weighing.
A mistake I have made with the wife. When I weighed with trailer had her get out to check placement on the scale pads. As a result the front axle lost some weight. I will never say how much though.

Putting 3000 lbs on a ball two inches behind the rear axle will remove 38 lbs from the front axle not 100 lbs; So the discrepancy is 62 lbs. If Andrew weighs 247 lbs and was sitting in the front seat (93 inches in front of the rear axle) when the truck was weighed empty and in the back seat (53 inches from the rear axle) when the truck was weighed loaded they would get the results they published.

I hope that you just needed a lot of trucks if you bought new ones in 88, 89, and 89.
