If you're still under the 5 year/100K mile warranty, take it to the dealer and let them fix it. They'll likely replace the entire little manifold on the side of the HFCM (the part that has the drain plug in its cover), especially since you have a 2003 truck which was covered by a TSB to replace that part when the water in fuel light would go off erroneously due to crud buildup.
The new part should come with a steel plug instead of brass, which will fix the problem permanently. You can live with that, or do what a lot of us have done and upgrade to the knurled-knob plug as used in the LCF trucks sold by Ford and International.

I haven't had this problem. But someone once recommended JB Welding the allen wrench to the stripped plug head to get it out. Of course you would want to have the replacement plug ready to put in. I'm not sure if this will work, but it's an idea worth considering anyhow. Good luck.

If the dealer won't fix free, you can use a center punch and hammer to remove it. Put center punch near outer diameter and start hitting with the hammer. Once it starts to dig in angle the punch so that it will loosen the plug and continue hitting it until it breaks it loose.
You might also try using the ball end of a ball peen hammer to hit the hex on the plug, this will flare some metal back into the hole and tighten the hex back up, then put your allen wrench back in and hit the allen wrench while trying to turn it.
These are old machinist / mechanic tricks that have worked for me in similar situations.

Of note here, after you get it fixed. The seal is accomplished by the o-ring, not torque. Just be really carefull when inserting the plug and only use mild force when torquing the wrench,
