GVWR minus max payload = 6,021 pounds for the empty SUV, not the published 5,838. But even the 6021 is not very meaningful. Since you now have the SUV, here's how to determine how much trailer you can tow without overloading the SUV.
Fill the SUV with everything that will be in it when towing, including driver, passengers, pets, cooler?, toys? tools, and the head from your weight-distributing (WD) hitch. If you don't have the WD hitch yet, then estimate 50 pounds.
Drive to a truck stop that has a certified automated truck (CAT) scale. Fill up with gas, then weigh the wet and loaded SUV, including driver and passengers and everything else that will be in it when towing. If you don't have the WD hitch yet, then add 50 pounds to the total weight of the SUV.
Subtract the weight of the wet and loaded SUV from the GVWR of the SUV. The answer is the max tongue weight of any TT you can tow without overloading your Yukon.
Divide that max hitch weight by 0.15 (15%), and the answer is the max GVWR of any TT you should consider towing with that SUV.

GVWR: 6900 lbs.
Dry Weight: 5,438 lbs.
Hitch Weight: 505 lbs.
If you load the TT to the max of 6,900 pounds, then you can expect tongue weight (hitch weight) up to about 1,035 pounds. Dry weights (including the dry hitch weight) are almost useless info. Assume your wet and loaded TT will weigh between 6,000 and 6,900 pounds, probably around 6,500 pounds, unless you are a stickler for making your wife leave stuff at home that she wants to bring on camping trips.
GVWR of your Yukon is 7,400, so with a hitch weight of 1,035 pounds that leaves 6365 pounds for the max weight of the wet and loaded SUV before you tied onto the trailer.
Your wet and loaded Yukon is probably going to wegh a lot more than 6,365 pounds, so you'll probably be overloaded.
If you follow the advice above, then you'll have enough information to make your own decision. I suspect you need to find a TT with a GVWR less than 6,000 pounds if you don't want to be overloaded with your precious family in the rig. Then minimize the weight in that 6,000-pound RV trailer so you don't exceed the GVWR of your Yukon.
GCWR is probably not a factor with your Yukon. If you don't exceed the GVWR, then you probably won't get even close to the GCWR.
