You hitch up with the armada off. Get done with hitching with everything including with weight distribution and lower the trailer all the waY so full weight on car. Then start car and listen for pumps to come on. You will see the rear end lift up and hear the pumps. When pumps stop you are done.Do you hitch up with the Armada running, or do you turn it off, while hitching, and raising the trailer tongue/rear of the Armada to get the weight distro bars on (for the pre-load)?
