engine overheats at idle, cools down when rpms up. Thinking it is a stuck thermostat. Have seen no leaks, truck was services not too long ago and all fluids cked at the time and OK.

This sounds like a radiator fan problem, I would start there.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
I have coolant leaking into my oil(engine), so it's head gasket or i was told its an air intake valve that goes through the throttle-body or a crack in the block...Drained oil, coolant and replaced...
Heater stopped working in the car and "engine coolant hot" light came on.
