There should be a caveat with N/A gaser tow ratings such as you loose X pounds of rating every Y feet above elevation instead of just saying it can tow 16,000 lbs. Unless doing 25 mph at 5,000 rpm without any power to pass is your idea of towing.

At the end of the test they were going 2600 RPM at 25 mph. Truck wouldn't downshift. I wonder what would have been different if they put it in manual. To be honest I never put mine in manual, but I have not towed the IKE.

They were screaming at 5,000 rpm most of the way when they were taking the noise measurement and they lost speed when it up-shifted until they got too low and it downshifted to high rpms again. In order to maintain a decent speed, it would have needed to be in the upper 5,000 rpm. That is not my idea of towing. GM should decrease the tow ratings for that altitude.
