Here's a good one

This was a post by someone on the TrailerLife board. I have no idea what forum here to put it in but this is the one I normally post in. This was a reply to a guy looking an '01 2500 with 5-speed and 2000 F250 with an automatic.



"I have had both Dodge and Ford diesels.



Dodge transmissions are too weak for the cummins torque and will wear out fast when used for towing heavy loads. The cummins engine itself is not too bad, although a lot louder ( noisier)than a Ford diesel.



The Ford diesel is made by International Harvester and has been around a lot longer than the cummins has.



Engine for engine, the Ford will out perform the Dodge every time. They are stronger when pulling up hill with a heavy load and they stay cooler than the Dodge.



Dollar for dollar, I would get the Ford.



But as has already been said... every one has their opinion. . So go with your "gut" feeling and not the paint job. . "

Being in the RV Biz, I have marveled at why they don't put Powerstrokes and Duramaxes in Big Class A Motorhomes being as they are so powerful and all... ... ... ... ... ... ... ...

Barry that is an excellant point and I would love to know how the gentlemen that wrote the original post would answer it. All I know is that the reason they sell all of the Ford PSD's and Chevy Dmax's is because most people are "not" motorheads. They don't do the research and buying a big truck is a compromise, a lot of people buy for the special features one brand might offer over another brand versus the best motor.

According to the Dodge Ram Brochure, the Cummins 40% fewer moving parts than it's competitors... What more compelling reason could there be?!?!??!

Also- I have been reading in forums here that Ford is putting Cummins Diesels in thier F550 series and up. Why not use the PoSD? Hmmm..... makes one wonder.

the cummins and cat are avalable in the f650 and bigger, not in the f550 iirc.

 

[Spooled-up]

Ford is putting the Cummins diesels in the 650s because they are part owner of Cummins of course. I thought you guys knew what you were talking about!!!

 

[MMeier]

Dorf has been putting Cummins in their s--- boxes for years now, anything to help move the things ,huh?

Yet another one from the same board...

Hello dear readers. I enjoyed reading your posts on the 3 diesels currently offered. I have owned my 1995 7. 3 TDI from new. We have towed 4x4s and vehicles across the country, with its 8' bed full of engines and transmissions, uphill through Utah at over 8000' at 75 miles/hr. No V-10 or any other gas engine can compare. I am absolutely sold on towing with diesel power.

I note, however, that we are now dealing with computer-controlled injection systems, intercooled turbos, and displacements that are very similar. The powerplants from a brake-horsepower standpoint are not all that different.



Therefore the topic we should really be talking about is the TRANSMISSION. The transmission offerings are more varied than the engines, from a techinical stanpoint. I believe any relevant discussion of comparison MUST include some cogent discussion of the drivetrain connected to the engine.



Both Ford and GM offer 5 speed automatics, which are absolutely neccessary since the reintroduction of over-55MPH driving. Diesels work more effieciently at low rpm WITH boost. The only way to do that is to use overdrives. I believe the Ford is now offering . 69 as the 2nd overdrive. The poor Dodge brothers, however, have saddled the 5. 9 with only a 4 spd.



Dodge, again, despite their 7/70 protection plan, have drivetrain reliability problems. Historically they have had ring gear failures, axle failures, and transmission weakness on the 5. 9 product line and some of the gas engine line.



GM's Allison transmission would be my vote, coupled with the 6. 0. I do not know enough about the E04D redesign to say anything about it. I do know the E04D with the 7. 3 215HP is barely durable enough for any real towing capability. I hope they have really upped the ante with the 5 speed.



I can also say this: the Navistar has the most advanced fuel delivery system of all the 3 engines. Both the GM and 5. 9 have steel tubes with flare-nut fittings connected to a centralized pump. The 7. 3 TDI is a beautifully integrated, cast-in system with high pressure oil-actuated injection. The 6. 0 is not quite as elegant, but I've read it is more leak-proof.



As for the future? Navistar is far ahead. Very soon they will have adapted the oil-actuated fuel injection system to create variable valve timing and get rid of the cam and pushrods alltogether.



The 6. 0 already checks manifold and boost pressures and temps. , as well as the mass air flow. Therefore valve timing is the only other parameter to be controlled. VVT will be necessary for increased emission reductions, while providing the final ultimate control over the torque curve.



On a final note, I have owned GM vehicles for years, and a few Fords. GM's weak point is their electronics. So for that reason alone, I would probably steer clear of the GM truck. The older Fords eat tires right and left, with an extremely weak front-end design for the 1200lb TDI. So that leaves me with weak drivetrains and a 4 spd. Dodge. I do know, however, that Dodge leads the front end with power rack and pinion steering, while GM and ford still have the ol' steering boxes. (I am on my 3rd in the Ford. )



So I need to be Johnny Cash (remember his Caddilac song where he stole parts every day?) Id like the Allison transmission and drivetrain with the 6. 0 Navistar in the Dodge chassis.

I think this guy is confused Wow, he can keep driving the Fords. I think I would disagree with almost everything he said.

 

[stevencarroll]

me to pit bull

I,ll take a bag of what ever hes smoking. I wonder if he ever goes to the dieselstop.com to read about how advanced navistar is. I wouldnt trade my cummins for 2 new 6. 0

 

[MMeier]

6. 0 Navistar???? Oh my god!!!! :--)
