I did say that one has to plug in the numbers based on his choice of trucks, mileage he will drive, fuel costs for his area, purchase price difference, etc. Even how many years he anticipates the truck lasting. Too make a purchase without doing so would not be wise. Many people that have bought diesels realized after the fact that a diesel was not the best choice for them. Remember just because something is an option and makes the truck more expensive does not make it the best choice for everyone.
