Big difference in both power and mileage. I have 2002 7.3 Excursion, and on the highway with aftermarket stuff done at all I get between 20-21 @ 65-70, there is " No " large gas engine that can do that. I also pull a 20' ski boat, that weighs in @ 5,000 with trailer, and I get between 16-19 depending on how many grades I have to go over, live in an mountianous area. No question about, diesel is the only way to go! Gas intial cost is less, but overall will cost you more in the long run.
