AS far as the dealer voiding the warranty on your D-max due to guages??hum, sounds little fishy....... First I have heard GM denying d-max warranty,Dont see that happen too much....Nor with the dodges,,,Ford is the one Known for that.. especially for having guages.... You could have beat that one.
I DONT think FORD would even pull that one on thier 6.0psd......

Naw, really? I thought all Chevy owners where in total bliss. 
To this date, my two worst trucks were a 1998 Chevy 305 and a 2001 Chevy 6.0L. One couldn't stay out of the shop and other had the infamous piston slap.
My 2003 Dmax was good until the LB7 injectors went south. Local Chevy dealer voided the injector warranty because of the egt guage. That was when I switched over to the 2007 Dodge 5.9L Cummins. I wish I still had that truck.

Spend a little time at the dieselplace, especially the LB7 section. Tons of injector failures and unscrupulous dealer service managers. Seems the injector issues were ironed out on the 2004.5 and up trucks.

Going from that 3500 to that 1500, it's gotta hurt, I'd be disgusted with the whole truck thing.

This Hemi is just a pee poor idea my wife talked me into. I guess it was her way of getting another new truck for herself. At least the 2006 Chevy 4.8L gets a consistent 19-20 mpg on the same drive (versus 14 mpg). BTW, the 4.8L has gotten 19-20 mpg since day one!
Reread my post!These trucks need to break in!Call it BS if you like,you are the one that came on here for advice.Whether you take it is up to you.If you try another dealer you may get some better results but the overwhelming majority of Hemi owners are happy.Good Luck

Just a little more BS to throw in. If you're too cheep to spend the extra dime a gallon for 89 octane and opt for 87 or 85 octane, you will likely see lower mileage due to knock sensors detecting detonation before you hear it and timing will be retarded to compensate for the cheeper gas.
Odd that the truck was totaled at a low $22k. To read here they're worth more at trade in than you pay for them. I'm also at a loss as to how one could afford a CTD Ram one month but not the next. Now they're even more affordable if Dodge wants to sell them. And at five times the mileage (one poster claimed a while back) the CTD Ram would be a couple of hundred a month cheeper than the Hemi powered Ram. Maybe there's a lot of BS floating about on internet forums?
Went from far superior to the Chevy to far inferior in one tank of gas... Hmm...

Hannibal, I think you might have missed my post (maybe not in this thread?) about the previous 2007 Cummins. When we purchased the 2007 Cummins last year we had a trade-in, a 2003 Dmax that had 1.5 years left on the note. This means we had a decent down payment that lowered our payments on the 2007 Cummins. This year when we bought the new 2008 we had no trade in equity and limited down payment money (no head start to save any). Also this past year we have had a reduction in income due to the failing economy (like many others). This should explain part of the budget dynamics.
As for the $22k total on the 2007, the body shop was still finding more stuff wrong including a bent frame (front), and a broken rear axle and springs from the wreck.
Hannibal, I would also like to thank you for your postings. You and your experiences were part of the reason I decided to accept the Hemi in the first place. Hopefully this is just a "growing" pain (very painful so far).
I am also going have the dealership check the fuel quality. Maybe we got some "bad" gas from our local filling station. Haven't had any fuel problems up to this point, but you never know?
PS. As for as the 2006 Chevy, we already owned it (wife's truck) and it was easier to drive the Chevy for a while instead of getting more mad at the Hemi. Drove the Hemi some this weekend everything doesn't seem so bad anymore.
Thanks for the help all.

Oh nooooo Mr. Bill!!!! Don't blame me! I've always tried to make clear as crystal that "I'm" happy with our Hemi powered Ram and that most others would not be due to it's powerband being higher in the rpm range. I hope you do grow to like it since you already own it. I got some watered down (I think) gas a few months ago when the E-10 first started showing up here. Mileage took a dive and it even stalled a couple of times while idling in gear. A couple of refills with Chevron and all was well again. Hopefully that's all it is. But, it's no BS that the 5.7L Hemi has a programmed break in period that runs the engine rich and at limited power for a set number of miles. Not really noticeable but you might. I either read about it in my owner's manual or on Allpar.com or some other credible source. Not just hearsay. From me to you it's just hearsay as I can't remember where to point you to a credible source but I'll see if I can dig it up. Also, http://www.dodgeram.org/ is a good source of information for both the CTD Ram and Hemi Ram. I can understand going from a CTD dually to a 1500 Hemi would be a big change, especially if it wasn't planned for. I made a decision to go from my fourth Cummins to the Hemi and knew what to expect before I made the decision so it's characteristics were no surprise. I've liked it for 91k miles. Hopefully you will too. But blame me? Now I won't sleep tonight...

Took the truck back to the dealer today complaining about the shifting up/down and fuel mileage.
Service manager gave me the same "all systems are normal" routine. Nothing wrong with the truck. Supposedly two techs that work for the dealership have the same truck and also get 13-15 mpg.
I now have 1,480 miles on the truck. First 2 tanks of fuel hand calculated to 15.5 mpg and 16.1 mpg. Every tank since has been 14.0 to 14.9 mpg. Today's fill up was 14.7 mpg.
Only modification to the truck was a Frontier brush guard (NOT the replacement bumper kind!)
I commute in the truck everyday, 40 miles one way.
12 miles at 60 mph, no traffic, cruise control on.
24 miles at 65 mph, light traffic, cruise control on.
4 miles light to medium traffic, 45 mph to 60 mph, 4 red lights, moderate traffic.
I drive "light and easy", no jackrabbit starts and all shifts under 2,700 rpms.
Same traffic conditions and speeds both morning and afternoon. Some rolling hills, mostly flat land.
Window Sticker EPA rating of 13 city, 17 highway.
Is my mileage numbers consistent with everyone else's or too low?

It sounds just about right to me. Its already been mentioned that the Hemi has a break in period. Thts going to count against you.
The EPA estimate is figured with an average highway speed of 48 mph. The max speed on the highway section is less than 60mph.
Take a look at how the EPA estimate is figured and you'll see that its gonna be a rare vehicle that attains their estimates.
The way the vehicle is tested is on the verge of rediculous. People just don't drive ther vehicles like that.

that mileage sounds about right, I had an 04 Ram QC 2wd with the 4.7 & my commuting mileage was right around 15 mpg IIRC...your truck isn't broken in yet especially with only highway miles so far, you might try swapping to full synthetic on your first oil change, that may help a little bit..
