What is the differences in the 2004.5 and the non 2004.5? I had a 1998.5 , it was a 24 valve with EFI instead of the 12 valve motor with standard injection, I loved that truck but needed a long bed and moved to Oregon where I really needed a 4 WHD so I bought a 2006 3500 4 WHD single wheel four door with the automatic, it rocks towing and non towing. It is my daily driver now. Is your motor the high output or ths standard motor? I have been told by several people I trust that the 2003 and 2004 get better mileage than the 2006 do I have a freind that had a 2005 4WHD 3500 dually with the automatic that towed his race car trailer, enclosed 24 Ft Pace Shadow and he had a 12.5 camper on it usually, I couldn't outrun him on the hills here in Oregon with my truck and same trailer with no camper on my truck It is really fun passing the other brands, especially the V10, on the hills

2003-2004 don't have the pre shot of fuel which I think were done to aid in quieting the engine down on later 05+ hence the reason for better fuel mileage.

4.5s have an external fuel pump and 05+ are in tank I believe.

This one has had the pump relocated in the tank I believe...atleast thats what the former owner said

the 03-04 HO were 305 hp and 555 of torque and were not 50 state legal because they did not come with a cat.you could only get a Super Output truck in calaforna.the 03-04 Ho trucks did not have the thired injection event. on the 04.5 to 07 5.9 the thired injection event was to keep the cat hot enough to help burn off the soot.thats why the 03-04 got the best fuel milage of the 03-07 5.9 trucks.04.5 was the frist year the ctd was 50 state legal and cam with 325 hp and 600 torque.in 05 they raised the numbers to 325/610

great looking truck you got. hope it serves you well. here is a pic of my daily driver/ tow truck. its a 07 6.7 with a few mods. mopar65

Now Cab, my V-10 pulled as well uphill as my (stock) CTD (towing the same camper)- it just did it at 7.5 mpg instead of 13.

I had the exact same experience. I have a 98 24valve now.I put bigger injectors, exhaust and a quadzilla box in it, now it blows the V10 away. AND it still gets 13mpg, even towing an almost 15,000lb trailer!

Hmmmm... maybe I need to look into a box for mine.
I've heard if I don't go too crazy with it mileage (and power [Tim Taylor voice] Ohhohhohh, more power... [/Tim Taylor voice] ) will increase but if I get too wild with it, it will puke the trans.
