diesel mileage on tow vehicles

As far as what is better you need to spend some time on the truck boards. it is kind of like the 8 3/4 vs dana or small block vs BB threads. Everybody has opinions and just like with most things in life, what "you" have is the best option in your opinion. Me personally, I am keeping this early 04 305 555 5.9 as long as I can.

I have an early 04 as well, and am very happy with it! I get about 18 mpg with normal everyday driving. If I am running empty I can get 19-20 mpg on the interstate running 70-75. Pulling my 38' enclosed I get around 11-13 mpg fully loaded. Although one time into a head wind I only got about 8.5 mpg running about 75 mph. I intend to keep this truck until the wheels fall off if I can! This is all hand calculated fuel mileage, as my trip computer seems to be about 3 mpg on the high side everytime I check it.

Caution to all of those beleiving the overhead fuel mileage marketing device, they lie Mine says a lot higher than the actual fuel that goes into the tank and the math for the mileage between fill ups

very true and in my opinion (unless you spend many many many minutes) to get an accurate hand calculated reading is install the famous vent kit. When I fill up (when I want to track mileage) I fill it until there is clear fuel (not foam) clear to the top of the filler neck. That way I know my numbers are fairly accurate.

I agree with this statement when checking the mileage by hand calc. My oferhead trip computer normally reads 27-28 and it has proven itself to be about 1-2 over actual most times.

I was very surprised at the increase in mileage that I got with the chip. My only mistake is that I waited 'till about 10k miles to get one. My next one will have a chip in it the first week I own it.

Funny, you'd say that; As you can see from my sig I have an '03 305/555, and '04.5 325/600, an '06 325/610 and an '08 6.7l and out of all of them, I like the 305/555 the best.

They are ALL good trucks and way better than the brand X's and Y's diesels that I've owned or still own.

The 305/555 is the last of the no-post injection event, no catalytic converter motors. Now keeping in mind that every one of my trucks is slightly different (different drivers, tires, accessories, etc.) so direct and exact comparisons are impossible, but my feeling is that the '03 gets about 1-2 mpg better than the '04 or '06 and 2-3 bettern than the 6.7. I also didn't care for the plastic intercooler tanks they used for awhile on the 325 motors and I feel the NV5600 is a better tranny than the later G56.

I've been running a smarty CaTCHER on the '03 for the last year (c/w gauges, of course) and couldn't be happier. Minor complaints are smoke on the higher settings and you need to watch the EGT gauge when towing heavy.

Your reasons are exactly why I specifically bought an early 2004 305/555 HO diesel Ram.
Remember, when you list the MPG comparisons of your trucks the 04 you mention is actually an 04.5 model which has the emissions, cat converter, and extra injection event.
My early 2004 has no cats, no emission hassles, no post injection event, and better mpg than the 2004.5 and later trucks.
Personally I like the looks and feel of the steering wheel in my 2004 better than the 2003 trucks.
I have a co-worker with a similar 2005 diesel Ram as mine. My truck ALWAYS gets better mpg than his.

My truck is all stock and has 110k trouble free miles on it.
It is my daily driver and I treat it like one of my classic Mopars.(It sure cost as much!)
It runs and drives like a brand new vehicle and I love driving it.
It still has it's original batteries, transmission, and believe it or not the original ball joints are still in good shape(I do plan to rebuilt the front end this spring just to be safe). I am VERY satisified with it.

With falling prices I have been tempted to buy a newer Diesel Ram truck but after seeing first hand the trouble some are having with carbon build up issues and poor power and MPG with the newer 6.7 diesel Rams I'll just stick with my 04, plus it's paid off.
I think the 2003 and early 2004 diesel Ram are the best, most fuel efficient quadcab Ram trucks Dodge ever built.
I have done research on the various programmers available but I've resisted the urge to install one as I don't need it to be a race truck, but the thought of even better MPG has my interest. I'm just leary of tearing up a tranny or cooking a turbo.
I also intend to drive mine until the wheels fall off.

Nice truck!

A couple comments;

- yes, the 2003 ETH's and 2004 ETH's (HO, 305/555) are identical motors and the trucks are 99.9% the same. I think the steering wheel and headrests are different. I try to refer to my 325/600 as a 2004.5 because of the Jan. 1st, 2004 engine change to meet the new emmissions requiremnets in effect as of that date.

- The programmers are nice, but unnecessary unless you are towing very heavy, in hilly country, and are impatient (unfortunately, I'm guilty on all three counts! ) I assume you have a 48RE and despite any naysaying from the brand X guys, it is a stout tranny. OTOH, it isn't quite as capable of withstanding upgraded power output as the manual trannies. I did have to replace the clutch with a South Bend unit, though.

- In all fairness to Cummins, the 6.7 is still a great engine. There are some issues with the new pollution control garbage, but that isn't really thier fault. The "other" guys motors have more and more crap on them too.

- You've got a great truck there. My advice is to just keep driving it. With an average life to overhaul of 440,000 miles, you aren't gonna wear out that CTD anytime soon!
