Then you’ll probably hate paying for diesel maintenance! There’s always a trade-off. You should compare the total cost of ownership over a year. It might not be as far apart as you think.
I’ve noticed the price difference between used 7.3 and 6.7 models isn’t as big in my area, so that makes the decision harder.

When you say ‘mileage,’ are you talking about fuel economy or range? If it’s range, that’s a valid concern. Gas trucks with short beds have smaller tanks, so you’ll be stopping more often on long trips.
