I took delivery of my 08 F350 DRW Crew Cab today and lucky for me it seems to have twice the power as the 08 I test before I ordered mine. As far as no the bad mileage issue I'm hearing about, my 04 PSD has had few problems but the mileage has been about 12 empty on the highway and 6-8 towing. I doubt it'l be much worse with the 08.
I'm anxious to try the 08 with 17000 lbs in tow...
