Towing with a 2016 GMC Yukon Denali

My vehicle is similar, a Tahoe. I wouldn’t “tow” more than 6000-6500 pounds while rated at a max of 8400. That’s loaded/wet weight, not dry weight. However, you need to “carry” weight too. Trailer tongue, hitch, people, stuff in the tow vehicle. What is your payload? Mine is 1595. Unfortunately you violated the rule...buy or select the trailer first, then match a tow vehicle. You don’t need to be an expert, but you need to learn. Do some reading. Yes, you need sway and a WD hitch but they don’t increase payload or max trailer weight. Again, do some reading before you buy anything else. I love my Tahoe but it won’t carry or pull everything.
