GM MPG must be embarrasing

[Black_Silver]

Pulling about 12,500# generally around 65MPH, my bone-stock Duramax/Allison gets 11-12MPG in flat country.

Man, last time I saw two "STAR PACKERS" side by side was in 1994.

Thanks for the Service,,, Hand Salute.

Carry on Sailor, no need to salute, I'll be in the area all afternoon. Take a break, and smoke 'em if you got 'em.

I have a 2003 Duramax. My daily commute which is slow and go to highway speed. I average 18 MPG. When I towed my last 5th wheel (weighing 9,500 pounds) I would average 10-12 MPG. Driving solo all highway I average 20-22 MPG. With my current 5th wheel (13,000 pounds) on a recent cross country I averaged 11 MPG. I hope this helps.

My new truck is getting 16.6 mpg driving around here. I have not towed the fiver yet. The old truck was getting 18-19 mpg around here and 11 mpg towing our fiver. It was a 03 2500 Duramax

...Ford has the tow rig, no doubt, with the tow boss rig in the one ton truck. All of us Dodge Guys have to wait for the Class 4 and 5 due out next year we all hope using the 6.7 Cummins at 325hp and 750 lbs/ft of torque, so werrrre told. Have to wait and see.

Dave,

Are the Dodge Cl 4/5 coming out in 07 or 08?

RSmoak,

This probably won't interest you as my mileage figures pertain to the Dodge with the Cummins engine. (For comparison since you weren't getting any responses).

1999 Dodge 2500 4WD Six speed w/ 3.54 rear end, towing a 14K fifth wheel (prior to MH purchase)...

14 - 16 highway towing
10 - 12 mountain towing

I used the Dodge as my daily driver when not towing. Here are some averages...

18 - 22 highway
17 - 19 mountains / city

A friend of mine has an 04 GMC with the Allison and Duramax. He claims 16 - 20 city / highway mileage. However, he does not tow anything heavy so can't help there.

If you plan on keeping the truck for a long time then the diesel will benefit you in maintenance and longevity. Unfortunately, fuel pricing has removed the benefit of less expense to operate (unless you drove it for a very long time).

Sorry if my information was not quite related to your question.

Just thought I'd give a response.

[CoastalDav]

ED;

Thats what the info is. The truck will be built
by Freightliner with Dodge body style. Its supposed to have a 6speed auto much like the Allison, or what is currently being used in the FL seris trucks.

The 3500 Chasis Cab that will be out in 2007 with the 6.7 cummins seems to have the frame and brakes to equal the Ford Tow Boss Package but is not rated in combined weight anywere close to the Ford. It has a 50 gallon fuel tank and the 6 speed auto or manual.

I think this is the second bad move by Dodge (DC). The first being their unwillingness to build a real crew cab and the second being the tow rating for the Chasis Cab. The specs for the frame shown on line sure look good.

i went and read dodge again
23k gcvwr seems a bit on the low side for a suposed 450 or 550 competion,
and only 16k trailer...tow rating
with 23k gcvwr, before you add a custom bed, it doesnt come with a pickup bed so add another 800 to 1k pounds so now we are left with 22k
chevy and ford will continue to eat their lunch

hower the 6 speed auto if its as good as the bigger ally world trannies that would be a big plus and compete hard with the torqueshift from ford.
may have to watch this one.

Hey Senior, there has not been a post or information yet on the 4500 or 5500 dodge truck,
as far as towing capacity and weight. I'm sure it will be equal to or more than (I doubt) to the equal freighliner truck.

Now if you put 750lbs of torque in a 3500, then your talking about something. But, of course, 750 ft/lbs of torque is only 500 dollars these days.

We will have to wait and see. A twin turbo 6.0 an't going no were since it will change the following year.

I was reading about it as maybe a new tow rig , but a chassis cab with less gcvwr than my current set up sort of threw me off.
but th e6 speed auto with a taller OD sounded promising, the 6,7 cummins really took it in the shorts HP wise with the new epa equipment , less hp then the 5.9, so that really makes me wonder what the 6.4 twins turbo is goin gto do.

Thanks everyone who responded to my question. It took a long time to get the responses I was looking for. I guess I should haave waited till winter to post the question.

Thanks,

Here is the lattest on the 6.7 Cummins.

350hp and 650ft/lbs torque. This will be available in 2500 and 3500 trucks as of 1 Jan 07. It will be available with the new 6 speed auto similar to the allison.

No info on increases in hp/tq for the chasis cab.

No info on combined GVW. Tow capacity is addressed at 16,400lbs.

Now if they will put that in a 3500 long bed crew cab dually, I might get real interested.

Here's a link to the press release via DodgeTalk.com

I just towed for the first time with my new duramax and it returned 9.8-10.2 MPG while towing our rig that is 9700lbs.

I only have 1700 miles on the truck so mileage shoud go up a bit in time.

empty we are getting 18.3 hand calculated.
