Well after some 75 year old woman felt she had to save two seconds and make a left turn into oncoming traffic failing to yield the right of way. I am sad to say my beloved awesome 2016 1500 limited in going to be pronounced and i will soon be in the horrible circuit of dealing with clown saleman that i will want to choke in the first 2 minutes im sure. Looking to go to a 2500 and it doesnt seem like there are many real options for power train other than 6.4 or I6 Cummins. Trans seam to be all the same, either the 8 speed or 68rfe 6 speed which ive heard has issues. What is all your opinions and input. Below is my baby after being punched in the face. I pull 7k pretty much max trailer.
I've had the 6.4 with a 6 speed behind it, and the 6.7 with a six speed behind it. They're really your only two engine options in the HD Ram trucks, they 5.7 is no longer available in it. Newer 6.4s have the 8 speed behind them, which from what I have read does improve driveability and mileage, but I didn't really have any issues with my 6 speed one.
If you buy a new one, take care of it and it will take care of you (don't rag on it, keep the fluids fresh and full, etc). My 6.4's only real issue at around 110k was the MAP sensor died and the truck wouldn't run, and it took them a good month to figure it out with a Chrysler engineer, because since it wouldn't run they couldn't pull good data off it. There have been, especially in older 6.4's, issues with the cam and lifters, but I haven't heard of many from the 2017 model year and newer. Remember, MOST people won't have any issues, forums will make any issue seem like a bigger problem than it really is for the most part.
The 6.7 itself is pretty stout, and as long as you don't go crazy with upping the power, the 6 speed behind it holds up pretty well for the most part. It does want to get into the highest gear possible as quickly as possible when you're cruising, so some guys lock it out of higher gears when driving around town. I personally don't, because I'm usually only at lower speeds for 3-5 minutes then I'm back to highway speeds. The biggest issues with the 6.7 (and really any diesel today) are the aftertreatment systems, DEF systems seem to clog up from time to time but it seems at least to me to be correlated with trucks that sit or idle a lot. DPF systems will clog up if regens aren't allowed to finish, or if you aren't working the motor hard (towing/driving at expressway speeds). Diesels have NEVER been happy just tooling around town, and the aftertreatment systems just make it worse.
If you aren't towing heavy, are just driving around town, or don't have a good reason for the higher fuel mileage of a diesel, I would suggest sticking with a gasser. I put a LOT of highway miles on my truck, and do about once a month pull a good size load, so the diesel made sense for me. In about 18 months I've put almost 30k on my truck, a good 10k of it pulling trailers. I did the same with my 6.4, in 5 years I put 110k on it, though not pulling near as much.
Ultimately it's up to you and what you want to do with it, but the general advice is that if you aren't pulling or driving a LOT, go for the gasser - it's cheaper to maintain if something should happen.
