Man, I don't want to change the pads out on a brand new truck. Not to mention it would seem this is a caliper/system issue, as opposed to a pad issue. It's an easy enough job but damn.... how many miles you have now?

Sorry, misunderstood you. Thought you had bought it lightly used.

Since this is still under warranty for a long time to come, you need to get the dealership involved. Even if it's intermittent, they need to build a service history on this in order to diagnose. Maybe it's something they've seen before. Optionally, you could jack up one wheel, turn it back and forth a little, depress and slowly release the brakes, rotate the wheel again, repeat, and see if it binds one time. As fkheath said, maybe the master cylinder is sticking now and then.

A little update to the story: I just drove 230 miles today throughout mountainous terrain and after stopping for the day my rotors were virtually cool to the touch. Maybe the removal and reinstallation fixed whatever issue I was having...... could not duplicate....
