Help Needed to pair new Tahoe w/ TT

I have to agree with Soundguy. I have a 2014 1500, 3:42, 6 speed trans, rawr is 3950 with combined 15000 weight rating. Trailer is 30' and 6500-6800lbs. A trip to the scales put me at 12800lbs range combined loaded and ready to camp. I am comfortable pulling with this combination although I have managed to be on a couple hills where I almost ran out of gas pedal. Sure, that Tahoe will "pull" that trailer, but I think you will quickly become dissatisfied with it. It will underperform and you will be at the top edge of control in my opinion. Tail wagging the dog situation.
Plus, you want LT tires on the tow vehicle and a min. load rating of "D" on the trailer tires. Pay attention to that.
