Not all Suburbans are the same. The 2000 was the GMT800 platform, which had the 5.3 and 4sp transmission. The 1999 was the GMT400 platform, and had the 5.7.
The 2000-2006 came with a variety of rear axles. These determine the tow capacity. These also came in three-quarter ton series, with 6.0 and 8.1 engine, and 2 rear axle choices. These ranged from 7500lb to 12000lb ratings.
