Ultimate payload monster?
What do you think is the top payload rating among new one-ton trucks? All the advertising goes toward horsepower/torque and towing capacity, but what configuration is king of payload?

Roy,
Larger trucks do and will have GCWR ratings per say. Not like pickups in that their is a single rating.
A given chassis drivetrain may have multiple ratings depending upon the end users needs. If used as a local delivery, gcw might be lower than an otr setup. Because local needs and wants say a 20-25% gradability, only 55 mph speeds on freeway. Meanwhile the otr setup wants 60mph, and only a max 15% gradeabilty.
It ultimately does get down to axle gears, tire diam, HP, torque, transmission gears ratios, number of gears....
Some rigs line my Navistar, reality is it's never supposed to be going down the road beyond manufactures gvw if 18200. Alot of us push this motor local deliver to 26000. It does not do real well beyond that. Even if it's level.

Hmm, that's something new to me. I did some Googling, and so far only found GCWR on Volvo tractors.
I went to Kenworth, on their MDs for example, it stated the transmission is rated to 58k lbs GCWR:

But Googling W990 GCWR showed no such spec:

The only tractor with a GCWR is their C500 heavy hauler, at 1/2 million lbs. But I guess that's a specialized tractor.
My thought is most Class 8 tractor components have GCWR well beyond hwy GVW limits, so they don't bother listing. Here in BC GVW maxes out at 140k lbs, and I've hauled nearly that in a run of the mill Freightliner with 46k rears.
