The cooling system may have a slight clog, it could be in the radiator or heater core. What I would do is drain the system with the engine cold and disconnect a heater core hose and back flush the system. Kits are available at most automotive stores. If the truck is heating up ther possibly be a clog in the heater core or it might have a vapor lock.
