6.4 fifth wheel hauler

[scrubbuck69]

Well guys, I went and did it. I bought an 08 f350 crew 4x4 dually with the 6.4 with 44,000 miles to pull my fifth wheel camper.
I know the mileage sucks on these trucks and am not real concerned about it. I only plan on putting about 5000 miles a year on the rig.
Are there any mods that I should consider to pull my 34' fifth wheel?
Exhaust, chips, programmers, cold air, etc.
I own a 03 7.3 liter that I can't seem to keep a trans in (edge CTS related) and don't want to make the same mistakes with this dually. Bone stock on the 6.4 might be just fine but am looking for any and all suggestions from you guys!
Please don't let me make the same mistake twice, my pockets are not that deep!!!!

I have the same truck, bought for the same reason. What I've done in the name of making it a better tow beast is DPF/ DOC delete, Spartan tuner, EGR delete, CCV mod, mag-hytec trans pan and rear air bags. Depending on the pin weight of the trailer you may not need the air bags (pin weight on mine is 3200 dry, so the bags help keep it level).
Tuner selection is personal preference but get one that has DPF and EGR removal capability ( by far the two most popular are Spartan and H&S). Getting rid of the DPF and the EGR systems are the most important, IMHO, for tow rig reliability.

Hes got it pretty well down

Camper weighs in at 11,400 empty and has 1900 lbs pin weight. I just put Firestone bags on my 7.3 but since that is going to be my everyday driver, I might put them on the dually just because.

Have you had ANY issues with your mods? I want this to be a dependable tow rig but wouldn't mind making some rice burners turn there head every now and then!!!

The only issue I've had was with a closed loop CCV mod that I bought. Caused me a turbo rebuild . I've since made a better one myself and got rid of the one I bought that was made out of PVC pipe and plastic pot scrubbers. The CCV mod is worthwhile and if you can stand the smell it’s easier /cheaper to just vent to atmosphere. But the importance of the CCV mod is minor compared to getting rid of the DPF and EGR systems.

You can see in my signature what I have done to mine to pull a 15,000# 5er around and to hopefully have no issues with it in the future, good luck have fun.

Still looking for any and all suggestions. I don't want to do anything internal or crazy, just bolt on and go stuff. Like I said, this truck is for only pulling my fifth wheel. We pulled 1500 miles one way to Glenwood Springs Colorado last September to do an elk hunt (no luck) and averaged about 7mpg. Did your mods help pulling and mileage?
Thanks for the input guys.

If you want to get better mileage towing, slow down. While towing, I never let the boost to go above 20 PSI. That equals about 63 MPH on the flats and if in hills it slows down depending on the hill to about 55. On a few steep long grades keeping it below 20 PSI it slows to the point of down shifting to 4th and the EGT's drop significantly. Mileage runs between 9.2 and 10.2 hand calculated. My fifth wheel is about the same as yours My mods are H&S Mini Max running on mild, 4" downpipe back exhaust and a SFE intake.
