I went through the same dilema when looking for my vehicle. At that time the '07.5 with the 6.7 were having quite a few issues with all the extra required pollution after treatments.. whether it be computer reflashes...trouble codes. etc. and the reported lower MPG. Of course there are the "for OFF Road USE ONLY" kits which helped with the problems. and there are some without any issues. I did not want to be Chrysler's guinea pig on the new '07.5 6.7.

Nor did I want to deal with the aftermarket DPF Kits and whether or not it poses a problem with any enforceable laws.

Many report here that the later models 6.7 such as the '08-'09 have had less issues.

If your just talking Engine that is.

Allready experiencing the "other" non Cummins Engine related truck issues.

Actually I like the 6.7 but I don't like all the emissions garbage it has to deal with.

For now I would look for a 5.9. Some time from now that may change as technology catches up to the 6.7 as it has done for the 5.9. Remember when the 12 Valves were all the rage and everything else was playing second fiddle? My how the times have changed! I expect the 6.7 to be the same way but, for now I would say 5.9 all the way.

Youre going to modify it why not have the bigger displacement? I havent had any troubles out of my truck and have 19k on it now. I love the 5.9 but I love my exhaust brake more.

I just went throught the same thing. Been researching since November and just finally bought a truck last week.

I had no intentions of buying a brand new truck, so that wasn't a concern for me.

The things that pointed me to the 5.9 were the fuel economy, lack of emissions control grabage, proven reliability and the plethora of available aftermarket parts.

That being said... The 6.7 comes with the 6 speed, but IF you are planing on many power mods, you will need to get a built tranny anyway, and can upgrade your trans then if you so desire.

There is also the issue of the emissions equipment DPF etc. It seems like a lot of the guys on this forum have that all figured out now, but I did not want to deal with the hassle when the 5.9 comes without all of that stuff...

The 6.7 has only 40 ft/lbs more torque and 25 more HP with .8L more displacement

The 5.9 gets significantly better fuel economy. On my Stock Megacab 3500, I get 18.8 MPG hwy, and about 15 MPG city (hand calc'd w/ 3.73 diffs). My father has a 2500 Mega 5.9 with intake/exhaust/bullydog etc, and he sees about 24 MPG hwy (hand calc'd w/ 3.73 diffs)

That was my experience and I am extremely happy with my 5.9.
