Sometimes if your tires are out of balance the truck can shake and/or shimmy, but only at certain speeds.
Just a thought. It's happened to me.

do you have a 2 piece driveshaft? if so its possible someone removed it to do u joints and installed it without lining up the u joints. the drive shaft is 0 balanced when they are lined up.

I'd bet it's your tires. Mine have 75% tread on them, but they've been plugged so many times that they won't balance. I start to shake a bit at 40, then it lightens off until about 65 and it gets pretty bad. I just can't justify spending $400 worth of tires on my $500 truck yet.

I wil add my experience here.
If you get a shimmy at certain speed range, then it goes away at higher speeds, then the culprit in most cases IS a tire with a broken belt.
Change the front tires to the rear and visa versa and see if this changes anything. If so, you have a bad tire.
BTW, a tire with a broken belt should be easy to find when you try to balance it. The tire shop guy will let you know if you have one after he is unsuccessfull in balancing it.
