Im in similar shoes. I have a 2010 Suburban with the exact same spec as yours. My TT GCWR is 5000 lbs. I live in Colorado so a lot of high elevation hills.
I added a transmission cooler and a brake controller. After a season of towing, I upgraded the 3.08 to 4.10 and was so much happier with towing and also driving in general. I think if you did what I did to the Suburban, you would be fine with the trailer mentioned in the original post.
Yep, gears make a huge difference. Especially when you are starting with 3.08's. I would love to try out a 6 speed (4.17 first gear), or the new 10 speed(4.69 first gear), with a 4.10 rear!
I bet they really get that load moving from a stop, plus they have better/multiple overdrive gears than my old 4 speed(3.06 first gear)...
The highest rated tow package(RPO Code K5L) for the OP's Suburban only lists a transmission and oil cooler, and 3.42 gears. Rated at 8300lbs. Same axles, springs, radiator, engine...all the expensive important stuff.
Another thing to check is tires. A lot of times the nice soft riding LT tires limit your tow rating.
