SAE J2807 defines the criteria for setting a weight. C&D offered a good summary. It is acceleration @ WOT based for the weight rating, which IMHO is not how most people drive.
That article is a little bit dated, but still probably relevant to matter at hand. I did find their guidelines to be funny. They want to try and level the playing field and make it more "real world", but those guidelines still don't accomplish that. Its more like those strong-man competitions that used to be real popular. They're measuring limited criteria on a brand new vehicle for short durations of time.
Climbing that grade at no less than 40 MPH for only 11 miles?
The acceleration times being tested??
Unfortunately, I didn't see anything in there about braking. Perhaps the truck can climb that grade just fine, but what's the trans temp once it reaches the top? How does the truck do coming down?
As APT said, these tests don't reflect how real people drive.
