Which of the big 3 makes the best overall truck/engine?

[Jbrow327]

Post 2012, which engine, gas or diesel, has the best pulling power and reliability in your experience?
In general, what's the most reliable post 2012 truck? For example, the cummins is good, but it doesn't mean anything if I have to replace the transmission or suspension before 100k miles.

pre 2012 probably a 6 speed cummins. but will have to do front ends yearly most likely
lml duramaxs are a good option and pretty reliable if you keep the motor stock
ford are a hit n miss.

ahhh yea read that wrong. dont think you can really go wrong with any. they all have their known issues.
I personally run a 2019 duramax 3500. and no issues yet at 110K

We could wander off to fantasy land and put say a 2015 Cummins and Allison together..

I drive a 2015 lml duramax at 126k now and only thing I've had is DEF heater go out (known issue). Knock on wood its been an amazing truck with hopefully another 200+ trouble free miles to go.

Limited experience with diesels but I’ve been driving a 2015 6.7l Cummins since purchasing it new. Right around 105k on it and I’ve been very pleased. I deleted and tuned it at around 80k when the DEF system crapped out and have been even happier with it. I’ve got buddies with newer Powerstrokes and they seem like a mixed bag in terms of reliability. No insight into Duramax.

Cummins/Asin is the way to go

My 2021 2500 D-Max is a hammer. It’s gonna stay with me for a long time. I can’t ask for anymore in a truck. I was just coming down a steep 4mi mountain the other day with 10k on the trailer and didn’t even have to put it in tow mode or touch the brakes. Just flip on the engine brake and sit back and ride it out to bottom of hill. Awesome truck.

I towed that load bout 300 miles and averages 10/11 mpg

But if I didn’t haul stuff pretty frequent or less than 8k I’d get the baby D-max in a sec. 30 mpg highway

So anything post 2012 will have DEF and each have there own issues with that. Deleting is an option but voids any warranty and some shops won’t touch it. Also the epa is cracking down on that. I’ve been told they are tracking exhaust orders online to find it. I think the Cummins 6.7 is the way to go personally. The newer 6.7 power strokes are good. If you are looking to drive it like a car then the smaller eco diesels are an option but that’s a different conversation all together.

I have a 2015 CTD 6.7 that is approaching 120k with the 68rfe. Deleted and tuned at 70k. Runs like a top so far, tranny is still nice. Tune was light, I would not have a problem buying a ford or a chevy through, They all have problems. I will say that an I6 is an advantage over the other two. The engine bay is pretty clean and not cluttered for repair sake.

Plus I think they look the best although subjective

Cummins with the Aisin or the G56/NV5400 manuals are the winners.
