What do I need to look for in a used Dodge

My son will be old enough to drive soon and he wants a Dodge 2500 Cummings. What do I need to look for in a used truck? Is the 12 valve better than the 24 valve or vice versa. What about the Tranny, he wants a Stick. I have heard alot of bad things about the auto Tranny on the Dodge. I am a 7.3 PSD owner and do not know much abou these trucks and I am sure this question has been asked countless times but any info will help. Also should we run the 2 Stroke oil mixed with diesel in this motor. I do in my 7.3 and have noticed a increase in my mileage.

Yes run two stroke oil!

I ran it in mine and I noticed it quieted the operation down more than any thing.

I would get a 24 valve truck personally. I just like how they put down more power from the factory.

Transmission wise, if its a 6 speed its an HO motor. If it is an auto or 5 speed then it is an SO motor.

I have a 24v truck. I like the fact that I can adjust the power through electronics, so if i want to run the track I can just turn up the box, or turn it down at other times. I have an automatic...which has costed some $$ to keep it together. The autos are a weak part of the drivetrain in the dodges.

My brother has a 12v...his first one was an auto..his new one is a manual. Neither one of them have given him any problems so far (except for the time when he was runnin low on ATF). If he plans on running more power for less cost, the 12v is the way to go. I've put about $9000 into my truck between a new injection pump, lift pump, gauges, tranny mods, injectors, exhaust, and a programmer. For my brothers 12v, we ground out the fuel plate, turned the starwheel, and put an exhaust on it and he runs right with me. Now he does need to put a set of gauges in, and should get a new clutch at some point, but for now it is alright.

So I guess I wouldn't say that one is better than the other, it's all personal preference and what he wants to do with it. Hope this is helpful.

I got one for sale but the price may seem high. But it's a extremely solid truck with nothing to worry about.

First off know it's a CUMMINS not cummings.. I would ask yourself what your looking to spend first then figure what that will buy you. The 24v are good just that there are no free power mods but the power can be adjusted up and down. the stick is a good choice just make sure to get a clutch that will hold up if your going to be adding some power. The 2stroke works the same in these too. first mod with a 24v is a fuel pressure gauge
the 12v is mechanically injected and there are a few free things you can do to turn the power up one them. Both good choices just need to know what your looking to spend and what that will buy you.

I personally say a 24V is better than 12V.

12V Trucks are good... But they require a lot of tool box time to tune in what you want. There is very little to none for adjusting the power for road conditions. (Snow / Icy Roads)

24V Trucks have there faults too. But Everything is Plug N' Play. All add on modules or programmers are VERY ADJUSTABLE and control fueling and timing easily without opening the hood or getting out a tool box. The HP gains with most boxes and programs will out do most "free mods" on a 12V

Like I got a buddy with a 12V 1992 Dodge with the VE pump cranked up he had to park his truck this winter because of the amount of torque it put out it absolutely un controllable. He doesn't want to de tune the pump to just drive it. Worse yet I've got his 3.2K Govern spring sitting on my desk and he really want to put it in but he know the added power won't be adjustable. So he's waiting for spring! :

Like in my case when the road condition get slick and icy. I grab the Edge Comp and select a lower level like 3x1 or 1x1. Either way I've only 33% of stock fuel till 20 PSI of boost is reach. So it really doggy in power and allows me to travel where he couldn't! When I clear the ice and get to black top again (Click Click Click!) back to 5x5 and I never got out of the truck!

As for 2 cycle oil... (Get a big cup of coffee!)

Manual trans are pretty tough... Auto's are just about worthless unless you dump serious money into it...

I would go 24v, b/c of the adjustable power, and b/c a nice 12v is honestly hard to find these days...Gauges, Lift Pump, Box or Programmer will be around 11 or 12 hundred...and South Bend right now has DD street clutches for 1k!!!!!! for Nv4500 and NV5600 2nd Gens...24s may cost more to get hp but in the long run the adjustability is well worth it imo...not if he wants to build a full time puller or drag truck b4 its all said and done then go 12v...and 24v (and 98 12vs which are uber rare) have better interior too...
