Regarding the 2500 Suburban, the tow ratings being based on drivetrain options, does the legal GCWR change? Whatever the legal GVWR or GCWR is for the 8.1, is that the same for the 6.0?
GCWR has zero legal merit. It's a manufacturer's recommendation based on performance and longevity. That said, grade-ability of the 6.0 isn't great. Get stopped on a 12% grade with that much weight, and you probably won't get going again without using low-range.
The GCWR of the 6.0 is only 16,000 pounds.
I have scaled twice that with a '15 6.0 and never had an issue starting. I pulled up and down the passes here and while slow, never got hot or ran out of power in full disclosure, I never ran Teton Pass at that weight. I would have zero issues pulling 11500 with a 6.0, especially with a 6 speed tranny and considering how very little air disturbance that. you get pulling a boat.
