More than likely your seeing air in the system.
Once the motor is fully warmed up turn the heater on full hot & do several 0-50mph WOT blasts. Do it again later as well.
The point being that the t-stat is closed 1/2 the time and just a single blast may not catch the stat open.
You could also do this in your driveway.. Drive the truck til it's fully warmed up. Then park it and set the parking brake.
Now put your hand on the top rad hose. You'll feel it get hotter / cooler over a few minutes time. When it *clearly* gets hotter the stat is opening. At this point free rev the motor suddenly. (with the heater on)
It's very UNLIKELY you have a bad stat. When a new one fails it does'nt open.
