When pulling 5/7 ton of hay or my 8,000 lb boat, I get 12 to 14mpg depending on which pass I'm pulling up here in Idaho and Utah. When running 60 to 70 mph I usually average 17.5mpg.

With my '92 F150 351w I average 15. With the cost of Diesel the cost of fuel per mile is a toss up, but there's quite a difference in acceleration and power.

A 7.3 is a completely different beast then the turbo 6.0 and dual turbo 6.4 that the EPA has desmogged and forced Ford to make better. So much "better" that they have a 100,000 mile warranty on the driveline to shut the irate owners up. The 7.3 WILL get that kind of mileage and often better. My '92 F250HD/351 would do 12-14 around town and 16-18 open road/empty. With my camper, 10-12.

And mine is NOT a diesel but an '06 V10, 6.8 gasser.

I've had the same thoughts for years. Even have two Honda Gold Wing 1000 engines waiting (H4's 125hp). Just never seem to find the time.
