Sorry Haonkered, I asked for more information, you gave some, but I have been away from my computer since then.
I was gonna post what cmbt suggested. You can call your local GMC dealer, give him your VIN, and they should be able to tell you whether your Yukon has the tow package, what final drive gearing you have (you may need the axle number from your driver's side door sticker), and also they might be able to give you what your tow ratings are.
