Truck running rough, need help!

Getting ready to leave on a camping trip tommorrow pulling my 38' 5th wheel. Late today it began running rough. It has a very choppy idle and gets worse when I accelerate and is noticable the entire time I drive it. There seems to be no loss of power. I have no check engine lights. I put it on a scanner and there are no codes. I did an injector buzz test and cylinder contribution tests and they were all good. ICP at idle is 530psi, IPR duty cycle is 9% at idle. I had just replaced my gray cps with a black one so for the heck of it I switched them back, but it still is running very rough. I checked all the wiring harness I could find.. My fuel psi is holding steady at 62. I just fueled it up today and put in a Standyne fuel additive. I have ran out of ideas.. Any help?
