I found some good info on my new Suburban in the trailer guide.

The Max Towing with the extra added oil coolers is nice. And long term you will need it, really need to watch trans temps and oil temps without those. Which I dont have but I do have a factory trailer brake controller. Odd they would do that.
Weight distributing hitch would be a must, no surprise there, watch your tongue weight, axle rating, and installed tire rating, as to not exceed you GVWR or the individual ratings of any item.
Unsure on tounge weight you can also use a bathroom scale with some wood set up that method is listed in most trailer owners manuals. It's a neat trick I ran across in my research, recently towed a 35' camper was about 9600lb with a different vehicle.
Weight Safe makes a neat ball mount with a built in scale for tounge weight. They are very slick products I have a Class V version no scale but very nice on a different truck.

GCWR (Gross Combined Weight Rating) for mine is listed in that guide at 14k. Would I feel comfortable towing at the upper end, nope.... says max trailer weight of 7,900 again for mine. Would have to weigh the truck with to get a base line. Since 7500 GVWR + 7900 GTW is 15,400 which is over the GCWR. Not sure what the buffer actually is loaded truck and trailer vs unloaded truck and trailer. There is no requirement for "Max Trailering" anything listed, just common sense applies these are not inexpensive vehicles so why beat them into the ground. Air Bags and coolers are the way to go if you can afford them.
Alot of the trailers are listed how they calculated the weight, with water, without... with fuel tanks full... ect..... look that up for the trailer you are looking at. Also alot of places will deliver and set up your trailer for you if you dont plan on moving around.
Do the homework, work out the math, happy motoring....
Here is what I moved last week, not with my Chevy. This would squat both my Chevy's. And be very unsafe.
