Anyone towing 17k GVWR 5er with 2004 GMC Sierra 3500?

Again, RAWR, FAWR, GVWR will all be listed on the tag on the drivers door post.
Took me all of 30 seconds to get to the 2004 TL towing ratings. Follow down to the GM/Chevrolet ratings, look near the bottom you will find 3500 listing with the D/A. The bottom one is when you look at the foot notes is a dually crew cab 4X4. If yours is not that configuration, you will have to look until you find your configuration. There is trailer towing ratings and another set of numbers for fifth wheel ratings.
