vibration ?

[CSMITH2011]

I bought a new 6.7 when they first come out , and loved the truck.
I never had any major issues with it. I have recently traded it for a Job 2 truck exactly like what I had except the color. This truck has a vibration that comes and goes when it's in a steady pull. has anybody else had this problem? Any help would be greatly appreciated.

I remember hearing someone saying they did somthing with the phasing of the drive shaft. But I can't remember, let me look real quick.
