That was back when. For 2005-up models, GVWR of the F-350 SRW diesel has been 11,500, but they have an option of 10,000 GVWR. The 10,000 GVWR pkg is simply a tax dodge, as the only thing that is changed is the sticker on the door that says what the GVWR is.
For 2013 models,
F-350 SRW diesel has GVWR of 11,500 (10,000 GVWR pkg is optional)
F-350 DRW diesel and F-450 DRW diesel both have GVWR of 14,000 pounds.
I don't know of any state that taxes personal vehicles based on GCWR (from which the tow rating or towing capacity is derived). But just in case, for 2013 models,
F-350 SRW diesel has GCWR of 23,500
F-350 DRW diesel has GCWR of 30,500
F-450 DRW diesel has GCWR of 33,000
If you dodge taxes by buying an F-350 SRW instead of a dually, you're probably going to be overloaded with the 16k trailer. If you choose CrewCab diesel 4x4 longbed, your wet and loaded tow vehicle is probably going to weigh about 8,500 to 9,000 when wet and loaded with people, tools, 5er hitch, bedliner, etc. A 16k wet and loaded 5er with 20% hitch weight will have hitch weight of 3200 pounds. If your F-350 SRW weighs 9,000 before you tie onto the trailer, you'll be overloaded by 700 pounds over the GVWR of the tow vehicle.
The newer Ford pickups are a lot heavier than your truck, so don't be surprised when your new truck hits the scales at 9,000 pounds wet and loaded for the road before you tie onto the trailer.
