I do not get how a Navigator can have a higher tow capacity then my 1997 F350 CC. I have the 10.75 Sterling rear and a Dana 60 front rear, t-case and 4.10's. A Navigator probably weighs as much too! Did thet revise how they derive GCWR on vehicles? There may be a small hp advantage, but not a torque advantage. I know which I'd feel more comfortable with in front of a 35 foot long trailer (wheelbase adds a lot of stability).
 
I guess this is why I am baffled by what I read what people are legally towing with. In no way am I criticizing the Navigator, but a 1 ton with leafs and solid axles is way more equipped to tow a load than a shorther wheelbase, IFS SUV.
 
The same truck, with a 460 gets 3,000 pounds more capacity, the diesel a whopping 7,000 pound increase; the difference being motor only. I believe it's even the sames trans on the 460(I believe both run the 4 speed OD-A40OD).
 
It doesn't make sense to me!

Yes I know the Nav. has a large towing capacity, I think it is because it has the 4R100 trans and the 9.75 rear end in it. The motor has 300hp and 355ftlbs of torque, and the rear end is the 3.73. It also has the 4 valve engine. All this was the same engine trans and rear end that they put on the 3/4 ton trucks in my model year.
 
It tows great with my trailer. I have a Drawtite hitch also that I set up pretty good too. It took me about a week to get it just right.
The Nav weighs in at around 6000# with me and a large tool box and other gear in it too. My GCVWR is 14500# on the Nav. too which is quite a bit more than your 1 ton. I dont get it either, but it works great for me. 
 
I also did a few mods to mine to get a bit more hp out of it as in I removed the clutch fan and added a '95 3.8L Ford Taurus fan with fan controller, and cut off the air chambers on the intake cowling and opened up where it goes through the fender to 3" dia. so it breaths alot better now, it is what I call the poor mans cold air intake, but that is it for the mods. (the cutting off the air chambers, and taking off the clutch fan  made a difference to it, I can feel it when I take off) It had 2 large air chambers on the cowling to reduce noise and probably for emissions.
 
So I dont know why yours has the rating that it does, maybe the frames are beefier now, I dont know.

I checked the numbers with Ford and in '03 the expedition has a higher GCWR then the F350CC with the same motor and gear ratios. It's also higher then the Excursion with the same engine/gear ratio combination. It's consistent. Maybe they are more conservative with the truck numbers due to likliehood of commercial use, or maybe the driveline/weight combo just pushes the small block too much.
 
I will do a cold air intake, headers and possibly evenan Edelbrock upper and lower intake to improve breathing. I think the electric fan may not be a bad idea either.
 
I will be fine with ZT30KB if I do not bring too much stuff; maybe I will go with a smaller trailer.  We'll go to the RV shows this fall and figure it out; I think I'll only be Zinger shopping!
 
Thanks for all your help. You confirmed what I already knew, but I wanted someone to tell me I can exceed my GCWR, no problem! It just can't happen. I also am shocked an expedition can out-tow a F350; it can!

Don't know if this applies to your F350, but my '97 F150 with 5.4L was rated as less hp then the 2000+ F150 w/5.4L.   They did something in 2000 which changed increased the hp.

I have a 5.8 Windsor, not the modular motor; I have an early '97 F350-the old body style. That is interesting though. Wonder what they did?
 
I have to say, I have always felt my truck is under-powered with the 5.8. When towing my boat through the mountains the mileage drops dramatically and out of OD she goes. The rest of the experience is fine; braking, stopping etc.
 
When I bought her, the 460 was not something I wanted to do, that is a killer motor but it is truly criminal how much gas it needs. A Powerstroke was too much additional money for an occasional tow vehicle/camper/work truck. The truck is a '97 and just truned 60,000 miles. A diesel would not like that-they need to be driven.
 
Now that I am going from small truck camper to towable, I may have re-thought that. Two weeks a year and a few weekends of towing should be fine, even if I am slow through the mountains. I will just watch my gauges and my weight!
 
Hey, the RV dealer was telling me some crazy stories about what people show up with trying to buy big fifth wheels and/or travel trailers. He told me one guy showed up with a Japanese truck (maybe that Honda SUV with the little bed in it) wanting a fifth wheel; it had a plastic bed!

It always been my understanding that trucks series F150, 250, 350 and 1500, 2500, 3500 isn't so much about towing capacity as it was more about payload. 

I'm sure your 350 can carry a lot more bed weight than a 150.
