"So…..The Diesel returned roughly 20% better MPG……but diesel fuel costs roughly 20% more…..so cost wise, it’s a wash."

Is not correct. 20% of two different numbers are not the same.

You did say your diesel was always 12-13 mpg no matter what. So lets say 12.5 mpg which if you deduct 20% brings you to 10 mpg. You state that your average was 9.34 mpg on your trip which is 25% less than 12.5.

You didn't state how much regular fuel was but according to gasbuddy it is around $2.90 in that region. That makes diesel $.58 cents higher at 20% which comes to $3.48. I very seriously doubt that it was this much of a difference especially since gas buddy shows $3.20 for diesel, but we will run with it.

So using these numbers with your diesel being at 12.5 mpg and your 6.4L at 9.34 mpg and gas being $2.90 with diesel being $.58 cents higher (again, I doubt this) at $3.48, the diesel would still come out cheaper over the course of your 2,700 mile trip by over $85 which is about the cost of another full-up. If you use the $3.20 cost for diesel that gas buddy states, then it would be a $147 difference.

Since you went there, don’t forget the cost difference of the Diesel engine over the gasser!

There is no cost difference. Keep the truck 10 years, resell, get 100% or more of diesel engine back over the value of a similar gasser.

I for one am happy for the OP. He has a solid tow rig that most importantly, suits his needs and he enjoys.

but, if you take that 9 grand savings between the gas/diesel engine, invest it over that 10 years in a good investment, assuming a 8% return...bla bla bla....

People find a way to justify anything. I think if you like gas, buy gas, if you like diesel, buy diesel. Any extreme justification of one's own choice to the internet just starts to read like desperation.
