Am I crazy for wanting a 6.0. I currently have a 2009 F250 with the v10 and 4.10 gears, its a very nice truck, Cabela's addition. The thing is I came from driving a diesel, 99 7.3 , for 15 years and miss the mileage that it gave me. I average just under 11 mpg with my v10 in mostly city, rural two lane roads. Ive drove a few 6.0's, I know the bad rap they get. The 6.0 will give me better empty and towing mpgs. We own a 30 5th wheel that weighs around 10,000 dry. Plus, we double two with the boat behind a few times a year. Towing mileage has been around 6-7 mpg. My old 7.3 always did 10-12 towing , always 65 mph and under. I only have 61000 miles on my current rig, found some 07's with under 70,000 miles for under $25000.
