Hello and welcome to just answer and allowing me to assist you.I see in your notes the coolant is going down in your coolant reservoir. does your truck have a coolant gauge in it and what does it read?Does the motor run like it has a slight miss, or rougher then normal idle? I will need your input to give me a idea whats going on so I may better help you.
