I have this exact truck with a HD towing package inlucded. How much does this increase the towing capacity?
it doesn't say which rearend or motor, but if you have the 5.3 and the 3.42 rear, it can tow up to 9500 lbs. properly equipped with a trailer brake. If you are talking about a trailer max pkg. with the 6.0 motor, it can tow up to 10700 lbs. I hope this helps. (rearend code in your glove box would be GU6 for a 3.42 or GT4 for a 3.73- if it is the 3.08, you can only tow about 6500 lbs.)
