Get a good fan and place in front of the truck blowing through the radiator. See if the temps drop. One thing a lot of people miss is closing the gaps off around the radiator shroud. You want to force the air through the radiator not around it. Air going through it is what will keep the AC nice and cold even if everything is working as it should if you are letting the incoming air go around the radiator it want never cool good.
