I have a 2002 Ford Diesel crew cab w/70,000 miles,7.3L engine and a 3.73 rear end ratio.
According to the Diesel Supplement Manual they provided originally with the truck, that configuration is good for a 20,000lb GCWR and a maximum 10,000lb trailer weight for a tag trailer. There is a note below the chart that says, "Fifth Wheel maximum trailer weights can be calculated by subtracting the GVW from the GVWR." In other words, 20,000lbs minus the ACTUAL weight of your truck equals the maximum 5th wheel weight your truck is rated to pull.
So what's the actual number for your truck? Depends how much it weighs, and your available payload over the rear axle. Run your truck over a scale and see how much it weighs, then check the REAR GAWR on the door sticker, and go from there.
