have you checked the front discs? if it does it only when its warm, my guess would be that the disc(s) is/are warped. most likely, its dragging and heating up the disc, then grabbing hard and pulling. replacing the rotors isn't that hard of a job, and it gives good access to check all the bearings and grease everything.
i had this problem once, stemmed from the fact that i had cracked the spindle, and it slowly drug, didn't notice it till later. i doubt that its that severe, but once you have the hub off, you'll notice if anything else is out of whack. make sure and grease and check everything while the hub is off

I don't - in fact, I'll promise you it's not the rotors.
Rotors are never going to cause a pull, unless they've both been turned and machined and one was done differently. If they've been on the truck for more than 5000 miles, then they aren't your problem. Plus, if they were warped, they would cause a pulsation when he applied the brakes.
I would bet that it's your front brake hoses. They deteriorate and collapse internally, causing excess pressure in the caliper after you release the brakes. This causes the pads to heat up and fade.

If it's brake related, then most likely the side that the truck is pulling away from is the one causing the problem.
Try this: take the truck for a ride, 15 mins or so. Then get out and see if one side is significantly hotter than the other. An infrared temp gun would be really handy, if you can borrow one.

How does it go down the road without your foot on the brake?
I would check and make sure you can move the calipers back and forth slightly with your hand so you know its not stuck on the slides. Make sure the right side brake lines arnt kinked. How do the rotors look?
Also have you inspected the left front wheel bearing?

If the rigid line has blockage you'll pull to the opposite direction. Even though you replaced the flex hoses, contamination could have previously backed up into the rigid lines. Flush the brake system, this will reveal if there is a problem in one or more of the rigid lines.
You could have an alignment problem instead.
