Could you please help me with my tow ratings on Tahoe?

My Tahoe was set up about the same as the OPs. I pulled at 5500 TT plus cargo, two kids and two dogs. I did it for 5 years. I knew my limitations and the Tahoe's limitations, how to load, where to load it, how to set up the WDH. I also saw Tahoes pulling 26-28' TT into campgrounds with their headlights pointing into the trees. Jonboats on the roof, 6-7 adults inside, etc. I was happy with my setup. It does not compare to my 2500 but that doesn't mean the Tahoe did a poor job, just that my 2500 is much better.
