How are the back brakes? Have you checked them? If the back ones are not working then your putting too much pressure on the front ones and thats causing the warping.
Good luck let us know!

Oops, I forgot to mention.
The rotors that warped last time, the rotors we replaced were on the rear axle. The fronts were fine.

Do you use the E BRAKE
after a long ride rotor get hot
did you check the caliper sliders

No, I rarely use the e-brake, and never with hot rotors.
(I was taught not to do that when I got my pilots license. Airplane rotors are very sensitive to that!)

First we need to clear up that "warping" of a rotor typically does not happen on regular passenger cars. You will see it only in extreme cases (i.E. Airplanes and auto racing). Driving your truck normally will not cause rotor warping.
What you are feeling is hot-spotting. This is where a hot section of the rotor causes a small amount of friction material to bond to the rotor. I would suggest changing to a higher grade of brake pad that dissipates heat better (i.E. Premium semi-metallics or ceramics). Then have the rotor resurfaced.
You should be able to get at least one cut from the rotor, unless the run-out is extremely bad.
