Did you check the trans mount with torque on it? Sometimes it is not visible unless you actualy have somone in the truck with it in gear while you are looking.

I must've been drinking when I answered that..
anyway...
if you're getting a vibration NOISE.. buzz, rattle, rumble, whine, etc..
you need to look for stuff that's LOOSE; mounts, shields, brackets...
if you can FEEL it, then you look at like things interfering with each other; exhaust hits on frame, etc...
now, with your truck being lifted, the change in driveline angles might have something to do with it as well...try (as odd as it my sound) removing the rear driveshaft and running it in reverse and see if it still does it.. at least you eliminate the "drive" parts of the equation..

Just be sure to give it pleanty of time to stop before shifting to park , maybe even shut it off .
