^PSN is a great place full of really great people and information.
If you are looking for an all around performer, I say go with the Ford. I would say stick with the 7.3 only because they are tried and true. My father has over 200K miles on his Excursion with the 7.3. The truck will fall apart before the engine.
Dodge- Of course they have a Cummins, but like everyone else has said, tranny, interior, and overall build is just suspect. But if you are looking for a truck that will tear a house down, then this is your option.
Chevy- Generally, now a days atleast, they are the over achiever of the bunch. They come with more power and are the quicker of the three. But believe it or not, the Allision(sp) is junk over the long haul especailly with any type of heavy loads or mods, unless corrected or preped with a shift kit atleast. Chevy tends to have the best ride quality out of the three. This is the truck you buy when you ocassionally haul/pull but mostly drive around. I also think they are the best on mileage. They tend to have issues with crank walk and piston/internals problems when higher hp are reached.
Interior-Ford
Exterior-The new Chevy & Dodge don't compare to the new Ford (IMO)
Hauling/Towing-Dodge...Ford...then Chevy
Ride Quality- Chevy
Tranny- Ford(5R111 Torqueshift is great), Chevy, Dodge
Build Quality-Chevy, Ford, Dodge
Stock Speed-Chevy, Ford(6.0), Dodge (atleast from my real world experiences)
Mods- Dodge all the way here, Ford (after studs,egr delete, gaskets), Chevy
Overall: For a daily driver that performs well in all categories, I would say go with the Ford. For a truck that you plan to mod or if you want a hot street/weekend warrior then go for the Dodge. If you are looking for a truck that has good ride and build quality but falls alittle short on the overall reliability then the Chevy is yours.
This next part is taken from Diesel Power Magazine: Top Ten Diesel Engines Ever Built:
#10. The Cummins B-Series
The One That Paved the Way
* Type and Description: Four-cycle, six-cylinder, inline
* Displacement: 359 ci (5.9L)
* Bore x Stroke: 4.02x4.72 in
* Fuel Injection: Electronic high-pressure common rail (current product)* Construction: Cast-iron block and head
* Compression Ratio: 17.2:1
* Maximum Power: 325 hp
* Maximum Torque: 610 lb-ft
* Why We Dig It: It wasn't the first, but the B-Series Cummins was the first to bring some respectability to the diesel in the pickup truck idea. It was good then, and it's simply fantastic now, with enough torque to relocate skyscrapers.
#6. GM 6.6L Duramax
The General Fires a Salvo
* Engine Type: Four-cycle, V-8
* Displacement: 403 ci (6.6L)
* Bore and Stroke: 4.06x3.9 in
* Aspiration: Turbocharged
* Fuel Delivery: Common rail Injection
* Governed Speed: 3,250 rpm
* Maximum Power: 360 hp
* Maximum Torque: 650 lb-ft
* Why We Dig It: After playing a distant third fiddle in the diesel marketplace, General Motors finally got mad enough to do something about it. With the introduction of the Isuzu-built Duramax in 2001, it got on the right track. The newest offering (the LBZ) is a refined beast capable of out-running the other two players in the Big Three's diesel power war.
#5. International 7.3L Power Stroke
2 Million Owners Can't Be Wrong
* Engine Type: Four-cycle, V-8
* Displacement: 444 ci (7.3L)
* Bore and Stroke: 4.11x4.18 in
* Fuel Delivery: Hydraulic Actuated
Electronically Controlled Unit Injection* Aspiration: Turbocharged
* Governed Speed: 2,600 rpm
* Maximum Power: 250 hp
* Maximum Torque: 525 lb-ft
* Why We Dig It: The Power Stroke introduced more truck owners in the U.S. market to the wonders of diesel grunt than any engine before or since. Reliable and readily available these engines helped to start a horsepower and torque race of nuclear proportions amongst the Big Three and push diesel ownership into the mainstream.
*PS* Sorry for the long post. Just lots of info to cover. Hopefully this helps you out some what.

actually, the dodges suck for towing, going up hills the stupid I6 can't make the rpm. The duramax and PSD are at the top of the pack for the consumer, but the ford truck is far better (solid front axle, better tranny, worlds better interior) the gm interior sucks, plain and simple, and in the new body style, the door panel is one piece plastic, looks like something fisher price would build.
Very true. Ya gotta figure when a bunch of guys who really know the PSD inside and out, for daily driven applications and performance applications, break-off from TDS and start a new PSD website, you're gonna get tons of great info from that kind of braintrust.

But doesn't their torque and power band actually make the low rpm pulling more efficient(sp I know) for the I6? Just a question, not saying your talking out your butt, but I would like to know.
There is a lot of truth to that! They have some of the fastest strokers on the planet over there plus I thing two of them have been in the Diesel Power Challenge. They know their stuff for sure.:thumbsup:
meh..i really like my cummins....and really like my parents powerstrokes 7.3 and 6.0 but they have both had more problems than i have had...and mine is hopped up alittle...
.. but it think its just about ur personal preferance...what ever makes u happy...just not a chevy lol

Might consider driving one of them before you try to lead someone on this path :idea: The I-6 makes more torque down low.
First you need to drive them all. Then take into consideration what you want in terms of comfort and road manners and consider what you will be doing with the truck. I would buy an earlier duty (99-01), replace the ball joints and tie rods with burly shit and drive it until the wheels fall off. My brother has owned his 03 duramax for over a year and has not had any issues after 80k, I replaced his pitman and idler arms after we rolled said truck last year...we drove away and the truck was sound mechanically.
IFS 3/4 ton still pisses me off in the gm's, harder and more expensive to lift but you can clear 33's stock with a t-bar crank and some really good shocks. The chevy will ride much better than the fords or dodges but it depends on how much of a pussy you want your truck to be. My bro's rides somewhat stiff but you can log plenty of hours in comfort. Based off all my customer's trucks and countless hours driving all brands I would buy a 7.3 or an lb7 duramax cuz I'm broke. If you have some bucks to drop buy an 04.5+ dodge and level it on 35's with rancho rs9000xl shocks or get a newer lbz duramax (06-07) due to the 6 speed allison and level it on 33's like my brother's truck
I would buy the chevy for the motor/trans regardless of manufacturer. Drives better, gets 24mpg, and tows upwards of 24,000lbs. The dodge will get 20mpg and beat the shit out of you and the 7.3 is loud as shit and rides rough unless you get some good suspension, they get good mileage tuned too.

What are the mods on he CRD's hitting 4k rpm??
I think it's some type of new beta testing(?) tuning whether it be a box or whatever I'm not sure but I guess without really knowing I'm not much of help. What do the Cummins generally max out on RPMs anyway? Whether it be a 12valve, 24valve, Common Rail? I imagine the power feels different in the RPMs if they are going up to 4K now? Especially at peak levels.
I know the Cummins can take the power, but I'm also not sure if there's any required engine mods to handle the 4K Rpm.
4K sure seems like a lot compared to my 7.3.
with increased hp- cummins have head gasket failures, LBZ duramax's melt pistons, 6L psd's lift heads/pop gaskets also.
Right, well we all know the issues with extreme cylinder pressures, heat, etc. etc. etc., but those are usually contributing failures dealt with the nature of the beast, such as the RPMs we're limited to.
4,000RPMs to me is a lot in a Diesel, I know Europe is probably past that but as far as domestics are concerned, I was curious about the mechanical ability to handle the increased RPMs as it wasn't designed to go that far up originally.
Another thing in my mind is with higher RPMs is to relieve the stress on creating a ton of power at such low RPMs? This might not be a correct thought process, but I don't see why else you'd want to go that high in RPMs?
Again, it's just an idea I threw out at 11 oclock at night. lol

What do you consider increased HP?? I've been around tons of "increased HP" diesels of all sorts that haven't had the issues that you state. Several have, its all about the combonation and the idiot behind the wheel.
I'd like to see the dyno-chart on one of these 4k rpm cummins dyno. All of the cummins I've been around didn't need to turn that tight of rpm. It was hard to adjust towing with my stroker and my dads cummins, mod for mod. Stroker had to be wound up 2k + rpm, where the cummins started to pull at around 1200, and just loved to sit down there and grunt and pull.

My Dad has a 2000 F-250 2WD and as of today it had 335,XXX miles (mostly interstate miles) with no major problems, mostly just regular maintenance...although the passenger door no longer opens from the outside and he's hit 3 deer with it so it doesn't have a grill anymore. It's pretty ugly but it's still going. He hauls his JD 350b bulldozer a good bit and it tows like a champ. I can't comment on the other trucks but I know his has been a winner. Good Luck :thumbsup:
