I see you are a Ford man but you may want to look at this, check out {Texas Truck Rodeo} here. New for 2014 Dodge 1500 is coming out with a 3.0 diesel with 240 hp and 420 lb-ft of torque, and a towing capacity of 9,200 lbs. Has a 8 speed auto & get 27 mpg on the road. You will be at the upper end but looks like it would work for great for you. You may want to put Tmbrens on the back as you are close to max, had to put them on the back of our SRW F350 to stop folks from flashing there light at up at night when we were close to max.
Or keep the F250 & just get a VW TDI Jetta sport wagon 40+ mpg with lots of room. I looked at one a while back & was giving life time free oil change & life time drive train don't know if still are.
