6.7 Good Comments Only

I thought Iíd get a thread going that shares some of the good things folks have to say about the new 6.7. I purchased my new 2007 Laramie, 2500 Mega Cab about three weeks ago and have enjoyed it immensely. Iíve read all of the negative comments on this board and it now has me listening to every noise my truck makes as it drives down the road. I hope this note doesnít jinx me but Iíd like to hear from some other folks that are experiencing good things with their 6.7ís.

I stepped out on a limb with this purchase understanding that the 6.7 was a new design and saddled with additional environmental controls. In fact I bought the truck while my wife was out of town and I picked her up at the airport in it (thought I may have needed to sleep on the couch that night but she loved it). I needed a new truck and had confidence in Cummins to deliver. The jury is still out on whether or not they actually delivered but man I have to tell you I really like this truck. As a former 7.4L gasser, I canít begin to tell you how impressed I am with the power and torque. Un-fricking believable. However the best feature for towing has to be the exhaust break. I canít begin to tell you how nice that is when you come down some of the monster grades we have in Idaho, Montana, and Oregon. Granted Iím only towing an 8,000 trailer, but none the less, the combination of the 6 speed auto and exhaust break is unbelievable. In terms of mileage, with 2700 miles currently on the rig, it gets better each time I fill up. Around town Iím right at about 13 and while towing Iím close to 11. I think I need some more miles on it to get a good feel for the economy.

The fit and finish on the truck is nice although I do agree with a few folks on here that GM and Ford has done a nicer job. Again, I hope not to jinx myself but I have to believe there are other folks out there like me that are experencing some good thing with their new 6.7.

In any event, let me hear from you if you enjoy your new ride.

Thumbs up Good Comments

I'm a former Duramax (2003) owner and now own a 2007 6.7L 4x4 SRW 3500. My main reason I got rid of the Chevy was to get a long bed and go from 3/4 to 1 ton. The 300hp Duramax and 5 speed Allison were a great combination. All the power I needed and the Allison's grade braking was an added plus. I bought the 6.7 6 speed auto combination because the transmission had the same features as the Allison (ability to lock up the torque converter, tow/haul function) and I didn't want to go from a 5 speed to a 4 speed.

The 6.7 L engine has unbleavable low end torque, horsepower, and acceleration! The 6 speed auto/exhaust brake combination seems at least 2 to 3 times more effective in braking as the Duramax/Allison! Hardly ever need to touch the brakes comming down the steepest Sierra passes with my trailer in tow.

I just completed a 1500 mile round trip with my trailer and now have 3300 miles on the truck. I averaged 11.6 MPG with my new Dodge. I made the same trip last year with the Chevy and averaged 12.5 MPG. The Chevy had over 60,000 miles on it and appeared to finally be broken in. I think that the fuel mileage on the 6.7 is gonna settle down to a fairly respectable number.

Yes I'm satisfied with the 6.7 engine!

Gotta go out and drive it some more tonight.

I love my new 6.7L. I have about 5k miles on it and couldn't be happier! I am getting 18.6 on the hwy without a load and about 14 with my 7,400 lb boat. I had an 04 5.9 which was a great truck but the 6.7 pulls harder and the Jake brake is one hell of a feature!

I am very impressed with my 6.7! My truck has had no problems and it does what ever I ask to do and more! I can pull a 20,000# coal trailer and I do not even feel it behind me. The combination of the 6 speed auto and Jake make stopping almost fun. I have had no issues with power or with the emmission system. I trust Cummins and so far Cummins has not let me down. I am getting between 17mpg and 20mpg depending on what I am doing with the truck. My 6.7 is a true beast of a truck!

I replaced my 2003 RAM 2500 CTD 305/555 & NV5600 with what you see in the signature......my truck has been flawless. With the 350/650 6.7L and the 68RFE's gearing, I honestly believe this one will stay stock. The Electric Blue paint is great; the interior is nice & rattle-free, and the exhaust brake is awesome....even on the automatic trucks.

It was nine weeks from date of order to date of receipt.....and worth every minute. My mpg is slowly creeping up : 14.6, 14.6, 15.0, 15.1, 15.1.....and I'm only at 1,792 miles. I tow very infrequently and wanted the better rear springs of the 3500 but left off the training wheels........very happy with the Blue Bus.

Just joined the site because I have the new 07 6.7 mega cab 4x4. Traded my 00 7.3...love the stock 6.7 power which is better than my 7.3 w/140hp chip! Can't wait for my first long trip next week.
