Bugsey, I just got the new TL magazine with all the new truck tow ratings. What you ordered is rated 15,700 lbs IF it's a HO 6sp 4. 10. 13,700 if it's HO 6sp 3. 73. 12,900 if it's a non HO auto 4. 10. 10,900 if it's a non HO auto 3. 73. Calif non HOs are 1000lbs less. A 3500 QC LB 4x4 DRW HO 6sp 4. 10 is 15,350. 3. 73 is 13,350. TL doesn't give GCW wts. You better call FAST if you want to change your order. I tried to make a change the day after I ordered mine and it was already too late. Craig
