Bye bye 6.7

[domehead]

I have owned many different bikes, cars and trucks in my life time and driven even large array of vehicles. At any given time period you can look at you will find vehicles that are real dudes but at the same time frame you will also find the stars. I will not get into the merit of one truck over another but I tell you over all each one has a place and function it fills otherwise it will end up just as memories and in collections somewhere.

I like my dodge and I do enjoy driving it even through the MPG is not the best in the world it does function very well for the reason I purchased it. If I could have my dream truck I would build a cross between the big three. Each one can stand on its own right and the owners of said trucks are normal happy with their choice of truck.

One other footnote the heavy duty trucks that we buy as far as I can tell are not truly commercial trucks are they pressed into that roll yes but I think the overall design is more of a light duty type vehicle. If companies purchased this type of truck to haul heavy everyday with that in mind than it should be expected to have a higher rate of repair, but at the same time there was front end savings on the cost of said truck. So if someone wants to makes the heavy duty trucks into commercial trucks than there is a price to pay on the back end otherwise the same companies should go with a more commercial line truck that is rated for over the 26000K mark and get longer time between time failure.

Nobody said a Dodge pickup or cab and chassis is a commercial truck but the Cummins engine is. It was and still is used in all sorts of commercial applications includind medium duty trucks, boats, stationary power plants, etc. The Dodge WILL hold up extremely well in commercial hauling. There were several thousand of them engaged in daily commercial hauling in the RV industry and oilfield hotshotting.

As I wrote above, when you look at the three light truck offerings in personal service they all look similar and appear to be simply a matter of personal choice which one a buyer choses. Put all three in similar commercial hauling and there is no comparison. The Cummins powered Dodge Ram is a far superior light truck.

You have just stated again that this trucks are pressed into a commercial use which implies that either people or compnaies think that these trucks are rate at commercial level. You have never said that this trucks are at that level but others have.

His point is the 5. 9 and the 6. 7 (that is a 5. 9 just stroked and bored to get to the 6. 7) is an engine designed for medium duty applications up to 60K pounds GCVW and is still in use today as such. The towing of commercial use can be applied to the light duty application trucks when towing within the axle ratings of such. If you don't believe us, just ask someone who payed a hefty fine for towing commercial at or below the axle ratings of a light duty truck, with a Class C license. I maintain a commercial license, and is a burden of cost as well as a headache for me, but if I hook up and make some cash towing, my truck would be considered a commercial truck. I would never tow over the axle ratings due to the expensive fines if caught and HBarlow is not saying to do that as well, just look at some of his posts on this subject, he is very anal about that.

I never said anything about towing over the limit and HB has not either but what both of us have been talking about if the truck is being used as a private vs commerical use. What will break sooner than later on said trucks.

Do you have a point you wish to make or do you just want to be argumentive?

Well I can bet the 6. 0 PS will be the first to fail and then the Duramax and then the 6. 4 PS while the CTD will pass them by with many more trouble free miles. The 5. 9/6. 7 engine was/is designed for 60K GCVW and although me and HBarlow disagree on many subjects, this is one we do agree with.

Color me silly but if I need a truck for commerical use I'll buy a commercial duty truck. I'm under no illusions that my 3500 was built for medium duty use. Although the Cummins might be a medium duty motor, the rest of the regular Dodge pickup truck line is consumer grade.



Based on what I've read here, I'd probably look at a Dodge Cab/Chassis first if I was hauling RVs or my truck was going to be used on a farm or oil field. I'd also take a good look at a F550 or 650 with the Cummins option.

I think you mean F-650 or F-750. The F-550 is just another version of the same POS as an F-350/450 . . . 6. 0/6. 4 Navistar, weak five speed Furdomatic transmission, etc.

I wish the State of California would let me. The code word "commercial" does not mean that my 3500 C&C has to be rated for medium duty. It just means I make money using it for hire. The State of California as well as the Feds require me to treat it just like any other Commercial vehicle, even to the point I have to keep logs stop at all scales when required. Its actually better to use a regular 3500 pickup because, at least in California, they don't want you in the scales, even when towing a 35' gooseneck with a container on the trailer, just ask MMeier. But because my C&C is considered to be a tractor I have to go through the scales when towing for hire. Why would I spend the extra cash for a truck I don't need. The 5. 9/6. 7 CTD can and will last a life time, because it is under worked in its light duty application, and I will not tow medium duty loads.



If Ford were to offer a 350 C&C with a Cummins, I still would not buy it unless the Dodge CTD is out of production. Its really a shame Obama did what he did to Chrysler, just when the Dodge 4500 and 5500 started to catch on, he sells them out to the UAW and Fiat. :{

The point I have been making all along is that the heavy duty trucks we buy are not really a comerical level truck. And if someone or company purchase said truck for comerical use than it will have a higher rate of repair compare to a truck that was designed for that type of work regardles of brand.



The point was not based on just the engine the whole truck. None of us just drive our engine around but than again that maybe fun.

I hear what your saying about the conundrum with commercial trucks in Comnifornia. I'm surprised any trucking companies even do business over there.

Regarding the Fiat thing, I'm against Obama getting involved with the auto industry (or anything else for that matter). The bright side of the Fiat merger though, is that it will help ensure the survival of Chrysler, and thus the Dodge truck division and Jeep. I hope to have the option of buying another Dodge Ram and another Jeep... based on the jeep and truck I have now I am nothing but satisfied with both of them.

That is simply your opinion and not proven. I did not find your statement to be true when I was transporting RVs pulling heavy trailers almost every day and running 135,000 miles/year.

Agreed it's my opinion based on information that I have read about trucks.

 

[Alphacowboy]

FWI, the 6. 7lt in the Ram are NOT a stroked and bored 5. 9. Its a completely new setup, this was covered numerous times when the 6. 7 was announced. The rumor was started about the stoked and bored 5. 9 in the early rumors of what the next engine was going to be after the 5. 9. 6. 7lts was leaked and because there was an industrial version of the 5. 9 that was bored and stroked to get the 6. 7 everyone thought that is what we're getting. Cummins later issued information on the 6. 7 confirming the rumors about the 6. 7 were just that, rumors, and that the new 6. 7 was NOT a stroked and bored 5. 9.







Anyway, I just hope to own one some day. I want a 4th Gen 3500 Crew Cab badly... .

 

[RVTRKN]

Interesting, I was not aware of this, was their an article in the TDR mag/issues that explains this and which issue?

 

[HBarlow]

I think Alphacowboy is correct. The ISB6. 7 is not actually a bored and stroked ISB5. 9, I believe it is a new block casting but reportedly does use several of the same parts. Some things we read early on made us think is was simply a bored and stroked 5. 9.

The 6. 7 does have a larger bore and a longer stroke than the 5. 9 and it is easy to think it was achieved by boring and stroking because of the siamesed cylinder bores. I wonder, is the distance between center of each piston or cylinder bore to the next one in line the same measurement on both 5. 9 and 6. 7?

My 2cents... Sept brings out the 2010 models... along with it the new EPA requirements...

CTD meets and exceeds this... Lets see what Ferd and Chebby does now!!!

Hello MFenza,



Cummins and Dodge SHOULD have made it VERY PUBLIC that the 6. 7s NEED to be WORKED. I am aware of this and I don't know anybody that owns one. I only know this because I am a Cummins Enthusiast. I am NOT a fan of the electronic engines, only the MECHANICAL engines. I seek knowledge because it is something I am interested in. I am taking an educated guess that you are NOT a Cummins Enthusiast. Hey, that is OKAY but you should have consulted the TDR sooner (you are a member!) and I would have steered toward a 12V and you would be an enthusiast just as I am!
