There may be nothing actually wrong and it may just take getting used to.

But, checking all of the fasteners in the front end and steering to make sure that they are tight and adjusted correctly is something that one needs to do along with checking tire pressure and alignment.

If there is an area close by with very little or no traffic like an industrial area or huge parking lot that is empty at certain times I'd take it down there where I had plenty of room and play with it a bit to get the feel of it. See if it tracks right hands off the wheel and see if it returns to center and drives straight after making a turn.

It almost sounds like the power steering is working so well that you don't have a lot of feel to the steering and that is throwing you off a bit. I have never seen a chart on the pressure valves on GM power steering pumps but maybe someone has info on reducing the pressure a bit to increase the effort and feel on the steering just enough so that you can be more comfortable driving the truck.

I'd still make sure everything is tight and then put some miles on it to see If I got more comfortable driving it once I had a real feel of it. My bet is that if it's set right once you get a couple of hundred miles behind the wheel you will be quite comfortable driving it.
