As for fuel I did a rough calculation for a Full Timer doing 20,000 miles/year towing heavy. At 6 mpg with a gas engine that comes out to around $7700/year at $2.30 a gallon. For a diesel the numbers are $4600/year at 11 mpg and $2.99/gal which are the current fuel prices here. So about $3000 a year in fuel savings subtract $300 or so in extra DEF and oil change costs and you'll make up that $6000 price difference between the engines in 2 1/2 years.
