All other lights are working fine. I didn't dig into the issue tonight. I plan to get back out there tomorrow and see if I can track down a faulty wire or ground.
Any ideas?

There are no fuses for the headlights, so don't wear yourself out looking for one. The headlight switch has a built-in circuit breaker that automatically resets itself. Don't use W.A.G. techniques, and parts slinging hoping something sticks. Go here:

and download the proper wiring diagram for your truck. Start with the dimmer switch, use a voltmeter or 12V test light to check for continuity, bad switches, bad/corroded connections, burned/broken wires, etc...
