Jayco specs show a 9950 GVWR with a 3255 lb CCC. Dry gross weight from the factory is 6695 lbs and a small 1375 lb dry pin weight.
I doubt you can load 3255 lbs of "stuff" in the trailer so realistic your looking at around 8500 lb wet weight camper and a 1700-1900 lb wet pin weight. The F250 gasser will handle that much pin weight safey and easily.
A '09 F250 with the V10 has a 14k-16k 5th wheel tow rating so it will have plenty of get up and go for that smallish 5er. The '05 V-10 same truck shows a 12500 lb tow rating.
The new '12 F250 6.2 gas engine from Ford has a 12300 lb to 15800 lb tow rating so it will have no issues with a 8k - 10k lb trailer. The '05 5.4 gasser shows a 8500 to 1000 lb tow rating.
