sounds like BertP left out some actuals as usual when talking about something he doesn't own.

I don't own a CTD, but I have driven them and almost bought one.

power ..... from the PSD is a V8 and a higher rpm than the Cummins inline 6 low rpm engine that has peak torque at 1400-1600 rpm. The PSD is a little short on low rpm power vs the Cummins. Wind the PSD up and they are equal.

Since the CTD has 6 cylinders and the Dmax and PSD both have 8, for a given pwer output, the CTD has to develop 33% more power per cylinder than the DMax or PSD. That plus the fact that there are fewer power pulses per rpm is what causes the CTD (or any 6 cylinder engine) to vibrate more than an 8 (or 10 or 12 or...) cylinder engine.

fuel ecnomy .... the 6.0 PSD really struggles with fuel mpgs vs DMAX/Cummins. The poor milage ol' Bert referes to is a few '04.5 325/600 Cummins owners were complaning of lower than the '04 305/555 previous years models great fuel milage. The 325/600 Cummins still was getting better mpgs than the 6.0 PSD. Dodge came out with a TSB/flash that brought the mpgs up.

Struggle or not, I simply said that they all have approximately the same fuel consuption numbers. Dave stated that the CTD has superior numbers.

ease of maintence/costs ..... goes to the Cummins. Top loading 11 dollar Fleetguard/Cummins/MOPAR fuel filter/8 dollar oil filter along with a 7500/15000 mile oil change schedule/15 dollar Fleetguard air filter.

Dave siad ease of maintenance, not cost. Either way, though, it doesn't make a big difference. All three are approximately the same. Besides, except for filter and oil changes, not many pople do any maintenance on their diesels. Note that I didn't say that no one does their own maintenance, just that few do.

RELIABILITY .... this is the big difference. The Cummins has a 350000 mile fleet average before first overhaul record. The PSD is a 200000 mile, per Ford advertizing, life expectancy. The 6.0 PSD has no record for a fleet average yet and Ford is stopping production. The current new 6.4 PSD has no record either but hopefully Ford will get this one right.

Overhaul schedules and reliability are not the same thing. CTD's have had their reliability issues just like every other diesel and gasser out there.

To see for yourself about the 6.0 PSD check out thedieselstop.com web. To check on Dodge/Cummins see dieseltruckresource.com web.
Check them yourself and see the problems/issues/non issues for yourself

I am aware of them, Jim. I am not picking on any particular engine, just pointing out that the claims Dave made do not hold water. If you want to buy a CTD, go ahead. Buy two if you want. Just don't try to sell me a load of BS that it is vastly superior to anything else available on the market. It isn't.
