Welcome to the forum!
While I am not the expert on this subject, I will let you know what I've experienced with my truck until someone more knowledgable chimes in.
My truck has a slight shake upon take-off that lasts about 20ft as well and then from 47-49mph there is a little shake/bounce. I started off by having the tires rotated and balanced. No real help there. Next I took it to my local trusted mechanic and had him replace the U-joints on the driveshaft and put a new carrier bearing on. He then drove it with me and agreed with me there was still a shake and sent me to his driveline guy. Took it there and the guy looked at my truck and showed me the big factory balancer on the driveshaft from Ford and said that I was lucky it didn't shake more than it does.
Since all of this I have basically learned to live with it now. Sorry for the lengthy post with no real answer, but it may help you out with a starting point. Again, welcome to the forum. There is a lot of good knowledge here that repeatedly helps me out. Welcome to owning a Powerstroke too! I love my truck and wouldn't trade it for anything!!!
