There is a factory recall G28 that applies to this vehicle. It is for the shift interlock. Has this been done on your truck yet?
There is also an adjustment procedure for the shift interlock. Here is a picture and the instruction.
I would have the recall performed if not done already. Then focus on the adjustment.
If you step on the brake pedal, roll the key to the position just before it powers up everything you should be able to shift it to neutral and start it.
Let me know how that works.

Thanks for all of your help.
The only possibility that comes to mind is to disconnect the shift linkage at the steering column and see if the shift lever will move freely. This would eliminate the column as the source. This would also turn your focus on the shift interlock cable.
Just follow the previous instructions to gain access to the shift cable. It pops off rather easily with a screwdriver. See if the shift lever moves with the key turned to on. If it does then the cable is the source of the problem. If not then you've got issues in the column.
You can also disconnect the shift cable from the trans to see if that moves freely. With both ends of the cable off then it should move back and forth inside its housing. Let me know how all of this turns out and we can go from there.
