Glad you had a good trip with no problems. You should have installed the Eco-3 halfway through the trip to get a good check on it's effect.
Great that you had no more coolant loss. As I stated before, the Armada's coolant expansion tank is under full system pressure, unlike many other vehicles. It is very important to keep the cap tight on both the radiator and expansion tank.
