Not brand bashing, I think that everyone will agree that the cummins is probably the best small truck diesel out there, just go to fordcummins and take a look at the pic of a ford rod hanging next to a cummins, damn, there must be three times as much steel in that cummins, that's what finally convinced me. And no GPs. Unfortunately, the package that that baby comes in is lacking in several areas. I have owned two 3/4 ton Dodge vans, I have 5 friends that have Dodge trucks. Auto trans:three replaced, rear ends: two replaced, lots of fuel pumps, fuel gauges, trim items, shift levers, brake components, you name it, it seems there is always somebody that has an issue going on at any one time. My good friend just bought a cummins (note he doesn't say Dodge). He did his research and he has like three grand set aside just for repairs. A friend of mine owns a junk yard a he said they literally have a waiting list for Dodge truck parts. Dodges always bring high prices at the auctions because of high demand.
I knew a cattle rancher out in the eastern cascade mtns that had a '95 F350 'stroke with 900,000 miles and his only complaint was that he put two auto trannys in it. He worked that thing like nobody's business. His son bought a new 24v dodge and within three weeks was wishing that he had bought a Ford instead. $33,000 regret. I just can't recall other Ford owners having any complaints. Obviously, Fords are not perfect, they just don't seem to have pervasive problems. I think that if Ford could get ahold of that cummins 90% of small truck diesels would be Fords.
One more thing, if you didn't know about the world famous Dodge trannys you should definitly do some research before buying. Just call up some local junkyards and see what parts they have and what they don't, or at least what they sell more of. I am definitely a whatever good deal comes along brand doesn't make a difference kind of guy so I am trying to remain objective. Well, good luck
