decided on a new Mega Cab 2500.
Would you guys go for the 5.9 or the 6.7?
Which will get better mileage?

 

Just an idea, a search will show you lots of threads on this subject, and just as many ideas on it .

I went with the 2007 5.9 as soon as I heard there was a differant motor and trans, let alone all the new polution $$$$$$$$$$$
Good luck with which ever way you go

I'd say if you can still find a 5.9, go for that one. That new emissions crap doesn't sound too good so far.

 

No offense to anyone but for now ..... F a 6.7.

 

the 6.7 so far is not having the issues the ford 6.4L is having. . .however I would still hold off on the 6.7 untill more miles are logged on them to see how well the EGR and DPF holds up over time.

hoever I will say this. on other sites I frequent. . .there have been very few major issues with the 6.7L.

 

If I had the choice I would get the 5.9l although I curtain the 6.7l will be a fine truck once the bugs are out. I mean it's still a cummins

 

most of the problems I am seeing deal with the EPA commie CARB crap in the exhaust. a few injector failures, but they are running on average with the 5.9L HPCR's.

 

egr is death to a deisel i had a 2006 jeep liberty crd just go to lostkjs.com and read for yourself they are real touchy i would go for a 5.9
