It's probably a driveshaft angle problem. I'll bet you have a two piece driveshaft. The carrier bearing the middle of the shaft needs to be shimmed to change the angle.

How do you know what is the right angle or how much to shim it?
It's a known issue as Mark says. Mine only does it when I shift to quickly into reverse. If I come to a complete stop before shifting into reverse in doesn't do it.
It is "TSB 06-23-4 DRIVE-AWAY SHUDDER OR VIBRATION"

I highly doubt this is the issue. I had this on mine and it would only do it when loaded or towing a trailer.
The shudder he is referring to is either the snap ring about to let loose and grenade the tranny or the planetary pins walking out. Mine is now doing this about 1 out of 50 or 60 shifts. Feels like the transmission is falling out of the truck.

I can't comment on the shudder he is experiencing - only he can I suppose. I did not notice him talking about shifts.
The TSB is for the following:
Some 1999-2007 F-Super Duty vehicles may exhibit excessive drive-away shudder or vibration, under moderate to heavy acceleration from a stop. This may be due to driveline angle.
Also - the snap ring issue applied to the 2005's: It affected diesels from '05 Job 1 through 01/12/05 and gassers from '05 Job 1 through 01/14/05.
Missed the part about going up a hill, so I could be wrong.
The TSB and it's dates has diddly squat to do with the problem. I had an '04 that fell outside of the build dates that went through 2 OEM snap rings and cases. Went with an aftermarket snap ring and shift kit and the problem went away.
Mine was built in Sept '04. They also tried to tell me that it was our shifting that caused it to grenade, while they had 10 other trucks in for the same thing. I was not pleased. Said they wouldn't warranty it a second time, but they did. Lost a total of 6 weeks of work on this truck alone due to the POS snap ring.
You state in your profile that you have a 2005 and in your post you state that it was built in late 2004. That is what is stated by Ford as being applicable.
I would imagine that other year models may have a snap ring failure. As I understand it, the 2003's as a whole were not affected by the snap ring.
Sadly, Ford only notified folks w/ snow plow options - I can understand your frustration.

Also have a Jeep, but it isn't Ford related. So don't always go by the profile, as I can only list one, which is my daily driver. Although I do operate all of them throughout the year.
They all plow snow, my '05 550 lost the planetaries at a whopping 500 miles, in the middle of January. 2 weeks to repair. 3 days after this one went down, the above mentioned '04 lost the snap ring, 2 weeks for parts and repair, still in January. Little more than 1 year later, the '04 lost the snap ring again, 2 more weeks while being repaired.
All this in the winter, when I need my trucks because I made obligations to my customers and my employees. I did this not realizing that some idiot at Ford would design a crappy snap ring to soften the shifts on the tranny so the weekend warriors and grocery getters would stop complaining about hard shifts. And then get the runaround on top of it.
