Sorry, maybe I should have posted in question an answer section? Nope, in the truck forum.  But here is fine.

I bought a 2015 2500 4x4 with the 5.7 Hemi without MDS 383 HP and 400 TQ and really like it. It is a much different engine from the normal MDS 395 HP engine but hasn't been around long enough for long-term mileage testing, though I am sure it is pretty much the same as the regular 5.7 Hemi. I just turned 31K today coming back from Minnesnowta with nary a problem so far, I bought it in August last year.  I didn't but the 6.4 because of gas mileage concerns since I drive it daily, but also because it is only 410 HP and 429 torque, not that much different.  My truck hauls my 32' LQ trailer loaded at 11K lbs with no issues. Gets about the same mileage as my 2004 diesel got towing, but not as good mileage not towing. 
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

Well, you won't get 300k out of any of these new diesels without some expensive trinket failing on you.  or $120 oil changes or higher cost for fuel at the pumps, plus DEF$. When you have 200k on a 6.4 or 5.7 you will be able to pick up another engine for $1500 at the autowrecker and keep on truckin'. 6.4 is the best in your spec. 5.7 would be great for a regular cab long-box.

Show me these 1500 dollar engines please! Especially a a non 5.7 hemi, or even a 5.7 without a 100k.
