Ask a german how to pronounce it. Seeing as Rudolph Diesel was from Germany. Only time I've ever heard diesel pronounced with an S in it was when I was watching Trucks.

I would be willing to bet if you saw the data that the Dmax spits head gaskets a lot more than most are willing to admit. I lost one. I know others that have. No it's not a sure thing like injectors going on the Dmax but I think it's pretty well known among the service people that the Dmax is more likely to blow a head gasket than the Cummins.

HEY what happened at the Nationals in Indy? Dmax stole the stock class but after that Cummins ruled. No Fords.

I guess Cummins owners decided not to waste their time with the "weak" little stock class

Oh, BW....did anyone see the STUPID looking stacks that came outside of the bed on that srw 6.0? I saw that thing last year at Scheid's and thought he would be smart enough to take the idiotic things off after everyone in the stands was laughing at him.

BS hoot. Its easier to keep a head gaset on 4 cylinders than it is on a long 6 cylinder. You can run more boost on a dmax than a CTD without studs. Ive seen plenty of CTD guys admit it. Ask Got Juice. Im talking boost alone, not drugs. I see "studs and o-rings" in many aftermarket turbo'd CTD's signiture. Want to talk bottom end? The CTD is significantly stronger...Ill admit that any day of the week. You cant admit anything good about any other brand. YOU had an early 2001 truck, you added too much propane and you lost. Ive been running 45+ psi for 60k miles with not one problem. And my trans is running all stock hard parts...not many 47/48re's do. But oh yeah, I forgot the allison is a POS too. I never lose any coolant, except when I hit a deer and broke the radiator. Could have been worse tho, at least a tree didnt fall on it.

ben,

I don't argue with the facts on the high hp end but I will guarantee you the GM service teams see a higher rate of stock headgasket replacement than the Cummins dealerships do.

My 48RE is stock with 52,000 TST miles on her... holding up just fine.

I can't admit anything good about any other brand? I'm not that bad. I just see the Duramax thing as an alternative that didn't quite turn out to be what I wanted. I know when it's time to jump ship and that was three years ago

So what happened to the rise and take over by the mighty Duramax? After this year (INDY) I think a lot of people are re-thinking this whole thing.

Where's hdmike? My buddy?

Hoot 99.8% of people dont just suddenly change brand preference like that. Almost everyone seems to have ONE brand preference sort of hard wired into them. Whether they know it or not...they will never be truely happy unless they are driving that one brand. Say a guy really likes dodge trucks, thats his gut preference....but for whatever reason he sees some little gizmo on a ford and makes a split second impulse decision and buys a ford. Then 30 seconds after he buys the ford he realizes "wait....darn.....I probably shouldnt have done this because Ill never truely be happy with it". BUT he grumbles and sticks with the Ford because he has no legit excuse to go through all the trouble and $ to turn right around and sell it....so he waits and prays for something to happen with the truck that would give him a perfect excuse to dump it and buy what he REALLY wanted all along, a dodge.

People who say "Ive always had dodges...but I thought Id give the new ford a try" are FOS IMO. They are never going to be truely happy with that ford. I know no matter what happends I will always own a GM. Im not afraid to admit it. So say for example my truck loses a head gasket tomorrow and I get all steamed up and in that day or so that im REALLY mad and hate my truck I go buy a Ford.....I would go crazy after my anger towards that head gasket issue wore off.

Whether you will admit it or not, you've probably always been a dodge guy. But then for whatever reason you bought a duramax and then next week thought "arghh...I kinda sorta wanted a dodge underneath it all but oh well Ill keep this one and learn to love it". Then the head gasket blew (yes!!! something went wrong, strike one, if only one more thing would happen I would have an excuse to dump this and get a dodge...). THEN the tree fell on it. (jackpot!!! g'bye dmax, finally)

Thats just my oppinion how your situation worked.

duratothemax - I think you're right about being hard wired. I'm a chevy truck nut. Love'em. Wouldn't want any other truck.

But I sure am glad I bought by Dodge Cummins back in '99. Brand loyaty is a ignorant thing to hold on to. Sure am glad I let it go, or I would have bought a 6.5L turd.

Oh yea I've gone through the brand lover days. NO MORE. It's plain stupid. You could never had called me for wanting or even owning a Dodge truck... ever. But GM convinced me otherwise. I used to be a Ford FREAK years ago.

I was Ford for like 10 years.... then turned GM... now I own a Dodge and my wife drives a GM. We love both vehicles.

Really.... any more I stay open minded.

I disagree with the 99.8% being hard wired. I just don't think it's quite that high. I often find people who either shop price, are clueless about brand differences or buy for features.... regardless of brand.

I bought the Dodge on price alone. Wanted a GMC but they wanted too much money, I didn't like the little tires and low squat. The Dodge sacrifices in the interior build but makes up for it with by far the best engine. Won't buy a Ferd based on too many negative experiences in the past, although I love their new interiors. I am glad I bought the Dodge and will buy another... Cummins that is... I do wish they would make a better interior.

I am a Nissan man myself. SO, who cares. I have a Dodge/Cummins truck. I love staight 6 engines. I still have a 1975 Datsun 280z. I have had everything but a 240z and the new 350z and most of them with turbo's including the 1975 280z. Maintenance is always cheaper on an I-6. Always has, always will be. If Nissan came out with a 3500 DRW truck I would look at it hard for a couple of years before I considered buying. I do enjoy the Cummins engine.

As far as which truck will last the longest? It depends on the person. Some people can tear up anything and some people take extremely good care of there vehicles. Dosen't matter if it is a Ford, Chevy, Toyota, Nissan, Honda, Dodge, etc. Would I buy a Ford, No. Would I buy a Chevy, No, had a gasser and I was not impressed and worked on them and was still not impressed. I want torque and none of the V-8's have what an I-6 does down low where you need it. I have exploded many a manual tranny in my I-6 turbo. I had to upgrade to a tranny equal to the torque I was putting down. Just My opinion.
