I'm not a big Chevy fan but just for the say so, my Suburban 4x4 is rated to tow up to 12k. It has the Vortec 8.1, Allison transmission and 4.10 rear end. Best tow vehicle I've ever owned. Over the last 15 + years, I've had two F250's (one 6.9 ltr diesel - one gas 460 4x4), Bronco (351 4x4) and a Tahoe (350 4x4). None of these could tow like the Suburban. The flat torque curve (455 ft-lb worth) and longer wheelbase make a big difference.
I'm currently pulling a toy box (tax deductable cobra hauler) that weighs in at 6300# unloaded. Add the Cobra and gear for the weekend and I'm around 10,000#. Pulls it without any problems at all, even up hills at the speed limit. Of course we won't talk about gas mileage, even though this is my economy car (better mileage than my Cobra).
BTW, so far I am quite satisfied with the 'fit and finish' of this American made, Mexico assembled
SUV.
