I have an F250 with the 6.8. If I could convince my wife to spring for a new truck I'd buy the F150 ecoboost, with the HD payload package and max tow in a heartbeat.
A 9500 lbs trailer with 13% tongue weight is 1235 lbs. Even if it comes out of the factory with an actual weight of 2600 lbs on the rear axle, your still along ways from exceeding the 4800 RAWR. And with 2740 of payload, and a 1235 tongue weight, you still got lots of room for family and firewood.
I only have an 8,000 lbs trailer so i'm 1500 lbs lighter than what you're looking at. But I'd get rid of my beast and downsize in a heartbeat if my wife would let me.
