Crunched some numbers and in my situation, it would take 3.7 years to break even on a diesel figuring today's fuel prices and 17 mpg for a Hemi and 25 mpg for a diesel along with the maintenance and DEF. I can't guarantee that I'll have this truck in 3.7 years. LOL. If I did get the diesel it would be because I wanted it not because it made financial sense.
I'm also not crazy about a diesel with my driving habits. The truck gets driven 5 miles round trip in the mornings to drop the kiddo off at daycare and then I'm back in the company car. I'll typically drive the truck once a week to work just because, which would become more mandatory if we don't take a weekend trip so it could re-gen... I think I'll stick to the Hemi...
Here's the spreadsheet if anyone's interested.
