The owners manual does not state whether the 12,000 is bumper pull, goose neck, frame, or 5th wheel.
If your truck is an automatic the fifth wheel tow rating is 13,200 lbs. Manual transmissions are rated at 13,100 lbs. As for why the newer trucks have higher ratings, it is because of FACTORY upgrades to the frame strength, spring ratings and mounting upgrades, Engine power, transmission durability, and maybe the most important is the braking upgrades. As an example, my '08 F350 ( F 250 has the same tow rating ) CC long bed 4x2 with diesel, auto, and 3.73 gears is rated to pull 15,800 lbs if I recall correctly. There are quite a few upgrades since the '01 model year that allow a 2,600 lb increase in towing capacity. The 15,800 covers a lot of the fifth wheel RV's out there. Anyone towing a triple axle fifth wheel with a single rear wheel truck is out of compliance. Period. Should they be in an accident, there fault or not, they could be found negligent for towing over the rated capacity of their vehicle. Lawyers would have a field day with this! These very large and heavy fifth wheels is EXACTLY why Ford came out with the F-450 dually package. Some of the F-350 DRW packages can tow more than the 15,800 my SRW does, but for the big stuff the F-450 is the way to go.
