On the Road, overheating, help!

I had a hard day coming from Phoenix to Kingman AZ this afternoon. It is hot out, and I am grossed at 20k.
When I started climbing grades my heat guage would go to the red! I tried several things, turning the heater on full blast helped, and it seemed to be an "airspeed" related problem. If I slowed down, it only heated more! I stopped halfway up one grade to let it cool, idling did not seem to cool, it seemed to want to go hotter.
I found some relief if I could keep up the speed as much as possible, hit the hills as hard as the EGT would allow and the added air flow appeared to help the cooling, of course that kept the tranny locked up and avoided tranny heat into the cooling system as well. Coasting down hill of course cooled it back off. I am thinking maybe fan clutch? It seemed to get worse as the day wore on, even fairly level pulling was getting more heat showing on the guage than I wanted. I cannot recall ever having any overheating problems before this.
Suggestions anybody?
