I just drove the 2008 today. It also has the wide track and as you state the turning radius difference is HUGE.I also had an early '03 6.0 DRW CC and now an '08 Job 2 DRW CC. The '08 in my opinion is the much better truck. Like dieselmankane said, it starts at the touch of the key every morning and is smooth as can be. In my case with my '03, I had the leaf sprung front end 4x4. On my '08 I got the wide track front axle for the DRW so I had a HUGE change in turning radius. I am very happy about that but the difference in ride was also huge. Of course they went to the coil front ends in the 05MY so I couldn't tell you the difference on an '05-'07 and an '08.
I occasionally tow forklift trucks on a tiltdeck equipment trailer and it's around 15k loaded. The factory hitch has been adequate for the job. The truck pulls real nice too.
I too will be towing a tilt deck (Econoline 7 ton deck-over) with a 10,500 lb John Deere on it. so hearing your experience is very valuable. The F250 just isn't enough truck, especially at its age and service. I would be interested in hearing about your hitch set up.
From my first drive, I am really impressed with the truck.
