You say you checked the fan clutch audibly and visually. How about manually checking physical resistance in the clutch when hot?
I don't see any other stones you've left unturned. Seems that despite the harsh conditions, the truck got hot but it didn't get hot enough (yet) to cause any concern to the ECU or A/C. Perhaps you're still within the outermost boundaries of what is normal?
