The 12v is properly valved. :thumbsup The 12v is generally cheaper to bomb than the 24v. The 24v is more of a "plug and play" type for bombing. The 24v is more prone to having LP problems and also more electrical problems. The VP is also a known issue.

Welcome snowman, I,m new here also. I don't know much about 12v but I just got a new 24v, on the new trucks watch the payload the book the dealers give you says the payload on a 2500 is over 2000lbs and three different salesmen at different dealers all told me different numbers above 2000lbs. But after getting confused at this I called dodge. The payload for a 2500 quad cab 4x4 with ctd is 1,880lbs, so I went with the 3500 it has a payload of 2,710 still on the low side for a 1 ton. Just FYI.....

happy shoppin

My brother has a fleet of 24v's and he likes them. I personally prefer 12v because I am always broke and 12v are easier to bomb and tinker with.

I like 12 vavles much more cuz I hate all the stupid computer crap and sensors and blah blah blah! don't get me wrong I like the 24v cummins its just I don't like to rely on computers and such, plus i feel the power isn't the same as the mechnicals.

So are you saying this is the way to go or not? I had a 93 3/4 ton and it was fine had to get rid of it though, I'm looking for something that can tow something around 5k maybe more on occasion and a daily driver dependability is more important than anything else also what is "Bombing" ? Does the 12 valve have mech injectors and the 24 valve not? thanks

Both engines have mechanical injectors. The 12v have a mechanical fuel pump (P7100) that is concidered pretty much "bullet proof". The 24v has an electronicly controlled fuel pump (VP44) that has, shall we say, "some issues"? Actually, it is quicker to get more power out of the electronics since they are 'plug and play'. The 12v is generally cheaper to get more out of though.
