Careful. Ask Chevy to look in their book for the VEHICLE tongue weight spec. Not the receiver, the VEHICLE. It is likely 650#. Note you want 13% to 15% of the FULLY LOADED TT weight on the tongue. This means you max FULLY LOADERD TT weight is 5000#!!!!!!!!!!! If your TT is 4800# dry, you can only add 200#.
Check with Chevy, ask to see WRITTEN towing guide.
Definitely check, but the best way is to weight the setup you are planning to use, load the truck how you will take it camping, and visit a scale.
The rating that usually maxes out first on the Tahoe and Suburban is the RAWR (rear axle weight rating). This is given on the door tag for your rig. My '03 Tahoe has a 4200 RAWR (mine is 3.73 gears, the newer ones may be 3900 with the 3.42 gears) and my hitch has a 1000lb tongue weight limit for weight distributing. In reality with my Passport 238ML (3800 dry, 4500 as I have it loaded with gear, full propane and fresh tank), I'm good for about 800 on the tongue before I punish the rear axle, but unless I load it poorly I'm running about 550 lbs on the tongue. With the short wheelbase of the Tahoe I think 24 feet and 5000 pounds is the comfortable limit. The 5.3L with the 6 speed transmission will not have much trouble with this, but with the squishy coil spring rear and P rated tires the thing is going to porpoise a lot with a heavy trailer.
You aren't going to be able to use the 3rd row seats for passengers while towing a trailer over 5000 lbs without overloading the rear axle.
