6.4...

Any truck you buy will potentially have it's issues whether its a Dmax or the Powerstroke. The 6.0 looks like its already had quite a bit of work done. It is a later model and in stock form might not be as bad as some of these guys have made sure to point out.

If the 6.4 is in the budget, I would jump on it.

 

Drive them all, do your research, learn as much as you possibly can about them on the forums, and make the best possible decision you can for the truck that fits YOUR needs, don't let us pick YOUR truck, in the end YOU'RE the one that needs to be happy with the truck and how it performs

 

For the miles your looking at putting on there is only 1 truck I would consider. And you havent looked at that one yet. Strokers and Durmaxes are rated a 250K motor Cummins 350K.
Now I know there are Dmaxs and power strokes that go long after 250K but no matter what you should get more life out of a cummins plus oil changes and parts and service is cheaper on the cummins.

Only truck I would consider from the group your looking at is the Duramax. That 6.0 service history says it all. It was a piece of crap, Do you think it is fixed now
6.4 is a fuel hog, atleast in stock form.

 

Great advice here. You're buying it. Get the truck you like. All of the diesel manufacturers make pretty good engines and how long they last is usually dependent upon how it is used and maintained. For the stories of problems, I would bet that in many of the cases there is a back story that goes untold on these forums.....My opinion....

Funny, I never saw that rating anywhere that I looked before buying any diesel that I have owned. I couldn't prove it in any other places but the price of oil changes and typical services are more dependent on the particular repair shop than to the nameplate on the front. At least that is what I have seen in my area and with my truck and the rucks of friends around here.......Again, my opinion........
Stay safe out there.

Is a 7.3 in the options? It and the 12v are the perfect work trucks. They both have enough power, are drop dead relaible, get decent mileage. I wouldn't really get anything new without modding it to eliminate the emissions control.

 

Yes the rebuild interval on a Cummins is longer than the Dmax and Powerstroke. But that is just recommendations from the factory. A cummins that has been hot rodded will need to be rebuilt alot sooner than a Dmax that has been takin care of. Cummins are generally cheaper to rebuild. They have less moving parts and are simpler. But if you're going for either the Dmax or the Powerstrokes i would go with the Dmax hands down. Mainly because if you are getting an auto, nothing beats an Allison. Just my .02

 

I hear the torqshifts are pretty tough.

 

Before I start my rant, dont think Im knocking the Allison. Its a dang good tranny, but I think the Torqshift is better. I personally have never heard of either a Torqshift or Allison breaking at stock power levels, the difference is when you start adding power. The Allison in stock form doesnt like tunes over 70-90hp, they start slipping and can go into limp mode. I know numerous individuals with 6.4 PowerStrokes running Spartan 210 or 250 tunes (210hp and 250hp over stock, respectively) everyday with no problems. And they can hold the 310 tune for 1/4 mile runs and messing around, but theres no way I would run it everyday.

Just what I have seen

 

I agree sir but he said he was going to keep it stock. The 6.4 in stock form gets horrible mpgs. So comparing stock to stock with no plans to modify it, i think the Dmax would be the best.

 

Agreed about the mpgs. Actually if you look at my first post in this thread, I placed the LMM over the 6.4, I was just discussing trannies
