The answer is they could not pass the SAE test at any larger weight. My reason was the Allison 1000.
If you watched the video I posted last week the GM engineer was asked what did they do to improve the towing capacity by ~10k lbs and the engineer stated they improved the cooling system, rear axle, and drive train (place Allison transmission here).

Repeated hill starts would be the reason. Fact is the rear end is now a 3.42 and before it is as 3.73. Maybe stronger but not as easy to move the load unless first gear in the NEW trans is lower.
