This may help. I did weigh a loaded 2006 T2553 for tongue weight, Scroll down the list

That said, many of the manual hand crank jacks are 2,000# rated and is pretty standard. You really want the jack to have lots more power then the loaded tongue weight. When you hitch up the WD hitch, you need to lift the back of the truck some which is more then the loaded tongue weight.
Hope this helps
John
