Economics?

Like I said, this truck wouldn't be driven much. Maybe 3-4K miles per year.
Using todays fuel prices and your mileage numbers and figuring that an
equivalent diesel truck would cost me a good $3K more than the V10 version,
it would take between 11,500 and 16,450 miles to make up the difference on
fuel cost alone. In that scenario, it would be 3-5 years before I start
seeing any net savings.
