Well, if you want to know the "rest of the story" in my best Paul Harvey voice.
So a while back I changed the air bags and the leveling valve on the front suspension. After changing the leveling valve everything was working ok except when I put the coach in the raise mode it would start to dump air from the leveling valve once the arm on the leveling valve dropped below the center. I convinced myself that it was the six pack leaking past. So this project was to relocate the six pack and to put the rebuild kit in it. Well that did not change anything, it was still dumping air. So as a last resort (I did not want to bother him) I called a local guru who I knew could help be a sanity check and we talked it through. I decided I needed to go back and make sure that I had plumbed the leveling valve correctly and wouldn't you know that is the mistake I made. I had plumbed the air bag and air supply connections incorrectly on the leveling valve, I had them swapped on the wrong ports. I had the air bag on the bottom port and the supply on the middle port. I swapped the air lines and all is good now. The coach is airing up as it should now. Now I can reset my travel height and then check my toe setting on the front wheels.
See photo of how its supposed to be installed:
