I have a 2007 3500 6.7 Cummins. I get about 14.5 MPG when it is running. I would not recommend purchasing the 6.7 L engine. The check engine light is on more then it is in the shop. Three of first four weeks I owned it was in the shop. Now it is injectors which I can not get for six weeks. I am going to try to Lemon law it.

I have a 2007 also. My Truck is a Mega Cab dual rear wheel 4x4. I had about 3 weeks of down time in the 1st 30,000 miles. So far all that's wrong is the engine light stays on constant but I've noticed better fuel economy 16mpg. I now have 50,000 miles. There were two trucks at my local Dealership that were supposed to be lemon lawed. A big construction company from Tampa bought 40-50 units and two trucks with the 6.7L gave them a lot of problems. Those two were on a ranch or hunt preserve. I think people who drive local tend to have more problems with turbo and exhaust system.

Fuel economy is only what you make of it, for instance my 03 3500 fully stock gets 30.6 MPG, 55 mph that is. If you drive the tar out of it it gets worse. Shift patterns and acceleration are key factors in fuel economy.
#10 of 16 6.7 4.10 or 3.73 rear
Mar 05, 2009 (11:54 am)
currently have 2003- 2500 with hemi and 3.73. Mainly use truck to pull RV trailer.plan to move up to 5th wheel in the 14K to 16K lb. range.
from all Towing Guides I've looked at, I'll need the cummins/ 6 spd auto/4.10 set-up to get to the 16k. Hemi, with 6,500 (+/-) trailer getting about 7 to 9 mpg when towing. ( at about 60-65 mph) How's that going to compare to the 6.7 / 4.10.
Would REALLY like some actual experience ........going tomorrow to possibly buy
a 2009 3500 dually...............Thanks

Congratulations! You'll like the Dodge very much. I tow a fifth wheel horse trailer and have the single wheel axle. Fully loaded it pulls just fine. I kicked around the idea of a dually and talked to a number of people who towed 5th wheel RV's and horse trailers and most of them told me the single wheel towed just fine and got around 13-14 mpg while towing. I do have a buddy in construction who has a dually but his 5th wheel trailer pulls a large tractor/backhoe combo. Although the dually gets less mpg than the single (duallies have a lower gear ratio) he's happy with it because of its stability and it doesn't tend to get stuck in loose dirt or mud at work sites like the singles do. I also know some people who tow very large slide-in campers and they like the stability of the dually over the single as well. Duallies look awesome too. Either way, you'll enjoy your truck. Don't know if yours has the auto tranny or not but I have the 6 speed standard and I like it for towing way better than the auto. No burned up torque converters and there's no sensation of the trailer being back there unless I look behind me.

thanks for the reply.did get the 6 speed auto...still can't believe that the truck came standard with the engine brake.....now it's time for Huskey flaps........extang tri-fold...trailer brake......who said trucks can't be FUN
#14 of 16 Dodge Engine Brake
Mar 08, 2009 (8:23 pm)
I forgot to mention the engine brake. My standard tranny model came with the engine brake as standard equipment too and it works like a charm. Maintains its speed down steep hills even with a fully loaded horse trailer with no sensation they are about to run over me. Couple that with the cruise control and its all good. The heater also warms up faster with the engine brake on. The trailer brake (Prodigy) I got for mine came off my Ford. All I had to do was buy the Dodge adapter cable for the unit and it plugged right into the OEM harness under the dash. If you buy one for the Dodge it should have the Dodge cable with it.
#15 of 16 more info on the 6.7 please
Mar 26, 2009 (7:19 pm)
I am considering buying an 08 6.7 mega or QC 3500. I do love my 2006 6.0 F350 and have had good luck with it up until now... they don't know whats wrong with it yet. should find out tomorrow. gotta be injectors or something to do with the fuel supply. (176000 km / 105000 miles so far) anyways I get around 15 to 17 mpg. 11.5 towing my 14000 lb 5th wheel. I want this to go up and not down. so some more updates on the 6.7 mpg would be nice and other problems you guys have had.. my next truck will not be a new Ford due to the 6.4 being a big piece of junk. thx

it's been about 2 weeks now. have driven the 3500 about 750 miles, none with the rv except to change the hitch ( had to buy another "drop" hitch to match-up with my Rockwood (TT). Needed 9" drop!.
Truck is getting about 15mpg av. town and highway- without Trailer. 1st trip planned for Good Friday.
4.10 rear lists 16,500 lb. tow rate with dually...that's about 3K MORE than with the 3.73. Did not find too many with the 4.10 on Dealer's lots, so when we found one, we bought it ( got SUPER deal and super trade-in on our 2003 2500 Hemi).
Laramie Package adds alot of stuff..even got Moon Roof. missed 0% for 48 by 1 week, but 2.90 on 48 is still not bad......esp. with all the discounts and rebates.
Brother-in-Law has King Ranch..he's still up in the air about it..but it does have bigger cab than my Quad. Mega would have been nice..but we thought that 8' bed would be better for a big 5th Wheel ( after we sell the Boat).
New Brake Control ( Tekonsha P3) was just Plug and Play..with the pig-tails that came with the unit and the Dodge.( got for $130.00 on line)
all in all.happy so far
