Brake Pad Replacement....
I have 63K miles on my truck and even though the pads are not ready to be replaced, I will be replacing them with Hawk pads, My question is: has anyone done this without turning the rotors? My rotors are clean with no pulsation or scoring. Can I get away without doing the rotors?

You can, but you should "break the glaze".
I've seen quality shops successfully use a fairly-coarse sanding disk on a right-angle hand grinder with the lug nuts tightened and the disks turning on the hubs.
It leaves a spiral scratch pattern.

Well I'm sure there are lots of opinions on this subject, and here's mine.
I never turn rotors. If their run out is out of spec, they are replaced. Turning rotors will true a rotor to its hub, and removes material. Removing material reduces the rotor's mass, and allows the heat/cool cycles to happen faster, so... you may warp your rotors faster the next time.
Biggest thing is that on one piece rotors, when the friction surface "warps", it also can distort the hat area on your rotor. Turning the rotor will not fix the hat, only match the friction surface to the hat.
Some OE's install new rotors that are at "minimum thickness" when new (Volvo for instance), so the rotors will be replaced in lieu of resurfacing.
I'm on my second set (getting close to 3) of pads for the fronts. I do, however, burnish the rotor surface when changing pads, that's it.
