I'm curios about the 6.7.

I ordered my 2007 at end of 2006 so I could get the 5.9L as it was a proven reliable platform......never want to be 1st year guinea pig for new engine/controls.
We were going FT and I didn't need that worry or headache.....same reason I didn't go with a FORD at that time

The 6.7L went thru some 'learning curves' (software programing) and some turbo/variable vane exhaust braking issues. Replacements and cleaning ports installed along with operating procedure changes (leaving EB ON all time)
Were among issues I heard/read about.

In time the 6.7L has gained in popularity and reliability.

Still would go with my 5.9L :B

The 5.9 is a lot less complicated with a lot less emissions equipment. The 03 - 07 5.9 is one of the more sought after diesels.

In my mind, the biggest disadvantage is that it only has a 4 speed auto (that is more than capeable, but will run higher RPMs since it has two fewer gears). The other disadvantage is if you need the back seat, unless you get a MegaCab, they are a lot tighter than competitor crew cabs.

Dodge/RAM made a huge improvement to the trucks when they went to the 2010 body style IMO.

Now we can sit back and wait for our Fish(ing) friend to come and throw stones from what his "cousin" sees in the shop, or what he has heard from his sister in law's boyfriend's nephew's dog groomer.......

I had an 07 6.7 for 9 years... No real problems at all... I bought a 15 6.7 as replacement.

Over the 5.9 it had the integrated exhaust brake... I loved it.

If you're looking to buy a 2007 the 5.9 would be my choice. Had a 2007 3500 Megacab dually and only problem I had was the soot getting into my trailer through the slide seals. It was a good ole truck and did all the proper maintenance the book called for. Many trouble free miles and years. Now I have a 2011 with the 6.7 and 6spd auto tranny. Loved the ole 2007 but the 2011 is a whole different animal. Think I'll hold on to this one for awhile.
Oh and I'm not ashamed of changing brands, I use to be a Ford man.:B

The 6.7 is not a grocery getter, it needs to be worked or you will have problems with the emissions

If you are buying a mid 2000's Ram I would tell you to get the 5.9 CTD. The early 6.7 engines had some growing pains. The newer 6.7s with DEF and the redesigned frame are vastly superior... engine and the truck underneath it.

I drove my 08 daily..... short trips, long trips ....etc.... and it never ever missed a beat in 100k miles. My 14 now has 51k on it and I drive it the same also with zero issues......

Mine is a daily driver also and have had severalroblems with emissions.

Makes me wonder if there was some other glitch that was causing the issue. Maybe colder weather not allowing the catalyst to get hot enough....etc....

I had the 5.9 in my 2004 dually. Great truck, but no exhaust brake. I have had 3 more since and love the 6.7. Current one has 900 lbs of torque..
