Should I buy the 6.7 I-6 cummins or the new 6.4 Powerstroke... I need towing power and decent mpgs and long term reliability

I have the 6.7 Cummins, 30k on the odometer so far so good. Had a few lights come on when I first got it, but the dealer reprogrammed it and it's done fine since.

If I had it to do over again I would get a Ford 3/4 ton with a V10.

decent mpgs and long term reliability

This doesn't apply to any of the engines you listed the days are long long gone when diesels got good fuel mileage and were reliable.

The 6.7 suffers emmissions crap problem along with the 6.4.

My next truck is gas diesel isn't worth it you never recover the costs and resale value is a crock of chit. Anybody with knowlege about diesel trucks don't buy high mileage used diesel trucks.

Buy a used 5.9 cummins or a 7.3 powerstroke if you want good mpg's and reliability

Buy the Cummins. If you want the best of them get a used 5.9, but if a new one is your type of thing than the 6.7 is still a reliable and powerful piece.

6.7 will get the better fuel mileage out of the 2. However i have been talking with more people and the ones who have late 09's, and 2010 6.4's are reporting better fuel mileage. Getting closer to the 18-19 hwy range. (not duallys tho) The LMM Duramax and 6.7 cummins seem to be getting good fuel mileage numbers. around the 18+ highway numbers. My uncle SAYS hes getting 21 outta his 2wd Cummins dually, but i dont think i believe that. Also said hes getting 14 towing 15k#'s...I think hes getting a little heavy on the sauce.

The only thing that makes it a tough decision, is the Ford is a much comfier better built truck. Dodge is definitely much better than it ued to be, but still isnt up all the way.

Well since you didn't ask about the d-max - I have no comment!

Yeh you should look at the D-max.

I wont buy a GM i just cant either dodge or ford sorry no GM products for me

You know Cummins is a good engine, and the new HD body style sure does look nice.

If these are going to be brand new 2010 trucks then Dodge all the way. The Cummins doesn't have the urea system, just another system to worry about for emissions.

Well for reliability you cant go with the ford cuz the engine didnt even come out yet. My vote is d-max, but its not one of your choices.

Stay clear from the Ford 6.4. They're coming out with a new PowerStroke 6.7L next year. The 6.4 is plagued with some (but not all) of the problems of the 6.0L predecessor.

I'd get a Cummins, bar none. The 6.7L and later 5.9L have similar power ratings, and if you can get a good deal on a 6.7L I'd go for it. The 6.7L is the ONLY medium diesel engine that doesn't need Urea to be added to control emissions, meaning less overhead in the long run.

Maybe your Dodge dealers back east can sell a Dodge diesel out here on the West people are taking their new truck back and telling Dodge to stick it. Not many are impressed with the 6.7 especially when it breaks down and the dealer says sorry can't do anything for you.

There are quite a few 6.4 Fords on the road they probably out number any other brand.

All of them will get bad mpg compared to older models until you get the dpf off and reprogram them. I think you can't go wrong with any of the 3, each has it's problems none of them are trouble free.

08 cummins dually 4wd - 16,500 miles....not a hiccup.

15 mpg on the highway

If I had it to do over again I would get a Ford 3/4 ton with a V10.

No way in hell would I trade my 5.9 Cummins for a V10 gas.
