Try burping the system again. Take off the cap, start the truck and turn on the heat, let it warm up to operating temperature and raise the RPM up to 3000 and hold a few times. Do this till you get heat at idle and the thermostat has opened. Raise the RPM a few times after that. Keep the coolant level up.
