Ford vs Chevy vs Dodge - they all have their pluses and minuses, their high points and low points. I am on my 6th F250/F350 since 1985 so I have no complaints overall. If I was going to consider getting another F350 and since we longer tow a fifth wheel, I would go with the 6.2 or 7.3 gas options. I don't think the mileage discrepancy between diesel and gas is that big anymore. And even if it was, knocking 10 to 12K off the sticker by not getting the diesel option, buys a whole heck of a lot of gasoline.
