What's better? 6.4L or the Cummins Diesel in a 2500

Well I'm sure both can pretty much do the same job up to a point. But one may not last as many years as the other.
The maximum mileage you can expect from a 6.4 V8
Hemi is anything in excess of 250 000 miles.
The average mileage you can expect from the diesel is a million plus.
Average mpg is 15.7. Thats dodge saying it. If you baby it while driving it will be a bit more. I suggest a tuner if you get one.
The diesel depending how you set it up can be as much as 17, but can go up to 27 or 28 mpg if on a tuner.
Wait till one morning you start the 6.4 up and get covered by smoke. Won't happen all the time but will every once in a while. Some say its the pcv valve.
Don't be surprised that engine temp hits 225 just driving it around, Its the nature of the beast.
You will most likely still have the same cam and lifter issue like the 5.7.
You start pulling max trailer weight and thats where the diesel will excell over the gasser. You can't replace a diesel with a gasser. Nor for the gasser to be better up hills.
high-output 6.7-liter Cummins turbodiesel delivers 1,000 lb-ft of torque, along with 400 hp. That compacted graphite iron powerplant is mated to a six-speed automatic, as is the standard output (370 hp, 850 lb-ft) diesel. The 6.4-liter Hemi is still offered as well, making more Earthlike power numbers (410 hp, 429 lb-ft). Big difference if your looking pulling power. Not saying the gasser can not do it, but the diesel excells at pulling up a mountain.
I like the longhorn edition, different leather and similar electronic assembly as the 1500. And the fact they used real wood on dash and steering wheel.
The diesel has a column shift where the gasser will have a rotary switch. I like the charging setup. My phone is a Samsung and charges wirelessly. I like the air suspension. I can lower the truck when hitching up a fifth wheel.
The Cummins valve adjusters are different. I can get rid of almost all the ticks. Truck still has a bit of vibration at idle, but I have gotten used to it. Center console is plenty wide great for elbows of two people. Still like the hide out cubby hole.
The real heat/AC controls seperate from two sides is nice. I like the ac on me but my wife likes it warmer. We are in arizona so this works very well.
The Aisin tranny feels pretty solid, if I ever break it, it will be easy to beef it up on a rebuild. Still solid after 89,000. Tranny is a bit slow on gear changes but I deal with it, I won't make changes till its out of the extended warranty. My tuner is easy to put everything back to stock and most likely they will never know I use one.
With the HO I got the Aisin. A regular diesel gets the 68REF, and I have friends into their 3rd build.
Dodge did a good job making the coil loaded front smooth. Not sayingvi can't feel the road or bumps, but it doesn't bounce me around like my Silverado.
The adaptive brake control is super nice. One thing I havent figured out is while in cruise control in traffic up a hill is maxed at 35, but once there is no traffic the max speed climbs too. Ive tried to find out why, but haven't yet.
Overall I still like the diesel better for towing, not saying the gasser can't do it, but way better control upband down a hill. That counts.
I keep every truck I buy, even if it means up on blocks. Not interested in the 2020 yet. Might wait a few years to buy a new dodge ram. Each person has to make his own choice. I know someday I might have to replace that damn cp4 pump. But if I do I'm going to throw a cp3 in. Ive read where the cost of fixing the damage from a cp4.2 is about $8,000. Versus a change of $3500 for a cp3. But hopefully it fails while under warranty, once I get near the end of the extended. I'll dump that cp4.2
