I'm going to assume that its a 1500 Suburban with the 5.7L engine with 2WD.
A quick look at the towing guide (http://www.trailerlife.com/wp-content/uploads/2012/01/Trailer-Life-Towing-Guide-1999.pdf) reveals you can tow 6500 lbs. You need to have the upgraded transmission cooler & radiator.
If you have 4WD, you can tow less.
As Doug33 mentioned above, on the half-ton Suburbans, one typically runs out of payload before exceeding the tow rating.
If you happen to get a 2500 (3/4 ton) Suburban, the field opens a bit. From there, you would need to know:
Which engine does it have? 5.7, 6.5 diesel, 7.4?
Which rear end gear does it have? 3.73 or 4.10?
Most common are the 5.7 and the 7.4. 4WD tow rating is lower than listed:
5.7L Engine:
3.73 gears - 6000 lbs
4.10 gears - 7500 lbs
6.5 Diesel:
3.73 gears - 8000 lbs
4.10 gears - 8000 lbs
7.4L Engine:
3.73 gears - 8500 lbs
4.10 gears - 10000 lbs
