Water disappearing

I just replaced head, head gasket, water pump, radiator, thermostat, therm sensor, mass air flow sensor, radiator cap, spark plugs and wires. My truck keeps over heating so we put in a new temp sensor that seemed to keep it in the okay zone on gauge, but coolant is mysteriously disappearing. No leaks on ground, no leaks on carpet inside, I mean like a jug of coolant every time me I drive five miles. When I open the cap it gurgles.
I just drove it up a kind of steep hill a quarter of a mile and when got to the top my tires were wet on the passenger side and opened hood the over flow was full and foamy, coolant was on the ground looked like it came from overflow reservoir.
Please help
