2020 GMC

88 was personal SW K3500, 89, R3500 dump flatbed for work, Astro van for wife to haul kids around. Have two 2000s also, a C2500, and a safari van to replace the Astro. Usually 2-3 trucks for landscape biz running around......buying/replacing something every two to 4 years.

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

And this truck will still be a better truck than the first new one I had in 81! or 86, 88, 89, 89, 92, 96, 2000, 2005.........

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 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.

UH, the ONLY thing Allison is the name. They call it "Allison Branded" :R

Fake Allison sounds better! Wonder how much GM paid to use the name? Hope it works well, otherwise is will drag down the Allison name.

Now to no more torque management with RAM and GM's. I wonder what they have re-branded it as. Drive Train Protection Feature??????

Features List:
LT275/75R18E Tires
10 Speed Allison Transmission
Drive Train Protection
Fifth Wheel Puck System
DEF Fill Inside Fuel Door
In Bed Camera
etc
etc
etc

Keep it going, hilarious. You pistonheads are aware Allison Transmission was GM for around 78 years, and is still closely associated in many areas? 78 years is probably the average time since you all walked out of Jr High School I am guessing.

Have to love the truck threads when reading the comments and brand of truck shown in signatures. This thread is a great example. Title is 2020 GMC but 90% of posters don't have a GM, probably never had a GM, and probably never will have one. Funny stuff, made my morning, keep it up, Happy Independence day.

The video had a cutaway frame showing this.
It looked to me to be pretty close to 2".

Definantly NOT 5"

It could very well be that the hitch is only mounted 2 inches behind the rear axle..... in which case 3000 lbs placed on the hitch would take 38 lbs off the front axle. (On a CC short box)

As I mentioned on the other thread I will bet the centerline of ball is MORE than 2". That would make 100#. What is the distance in inches from axle to axle?

The wheelbase of the cc short box is 158.9 inches. For a 3000 lb pin to take 100 lbs off the front axle the ball would need to be 5.3" behind the rear axle.

Visually it appears more than 2” in video.
