I don't know about the tow weight questions but can offer some opinions on some other things.
I'm buying a new truck and went away from Chevy (currently in an 06 Duramax) because the 6.0 is underpowered compared to the competition.

I think Chevy offers the 6.0 this year with the 4.10 rear end to try and make up for relative lack of power. Fwiw, a buddy of mine tows an 8500lb TT with the 6.0 (3.73 axle though I think) and HATES it. It's a dog up any hills. With the weight you're talking I can't imagine you'll be pleased. Realistically, you are pretty close to diesel territory with 10-12K lbs.
...but I'm guessing Chevy isn't admitting its shortcomings.

I won't offer any opinions since the OP would be better served with some first hand accounts. I own a 6.0 with the 4.10 gear and have also 6.0s with the 3.73 for our company work trucks. The gear change certainly wasn't because the motor is a dog. My travel trailer is relatively light (approx 6k) and there is no issue taking it anywhere up or down any grade. Towing with heavy equipment such as Bobcats, backhoes, other full size trucks, 5 ton of rock, etc has caused no concern for driveability or safety. My truck is also set up for 5th wheel towing and I have used it to move my neighbors 9500lb 29' to a seasonal. There have been days when entering a town after driving in rural areas that we do forget we have something hitched in back. No it isn't a diesel but that isn't the topic at hand, and I won't speak for the other makes since we don't keep them in our fleet or for personal use. The 6.0 gas motor pulls like a beast and my daily driver has a payload of over 3k. Fuel mileage is about what you would expect- 13mpg unloaded and 10 mpg loaded on level ground. If someone is having power issues with their 6.0 they should have a checkup with the dealer, because the 3 that we use have never let us down.
