The pin weight number you listed is DRY not loaded ready to travel. Double that number and you will be far closer to an actual pin weight. Load the family up with everything you can think of and drive across a set of scales. I would be suprised if you dont weigh around 8000 pounds. Meaning your real life payload including a hitch will be around 3000 pounds. But you also have to understand a fivers pin weight, what ever it turns out to be is placed directly over the rear axle. Which is based on your rear tires load rating. Glad your asking first, but I would suggest you start looking at fiver with GVWR around 13,000 pounds.
