Tom,

I think the 18 lbs in half a day is significant. Here is why. On my coach it takes about 90 psi to float the front end. By float, I mean to supply enough pressure to the bags to get the coach to start raising from dead flat on the tires.

So really the pressure we are playing with is 120 lbs max air pressure on the supply side, and 90 lbs on the low side to float the coach. I really think that in 24 hours at that leak rate the front corner would drop inches. Making some crude leak rate calcs have you going from 120 psi to 80 in two days or so. That would be enough leak to allow the that bag to settle from full extension to no extension.

I got a good laugh at the mislabeled air lines. I have discovered this week that six pack orientation is NOT the same on all six packs Newell made. On some the up solenoid is in the middle, and on some the up is on the end. How do you tell? Look at the air supply line to the six pack. If it comes in on the end horizontally, away from the travel solenoids, the up will be on the end where the air supply line comes in. If the air supply line comes into roughly the center of the six pack vertically, then the up will be in the middle. And if you happen to have a six pack manifold made by HWH, it is plumbed way different than the ones Newell made. The point is, that it is not safe to make assumptions about the sixpack valves, it is best to confirm their identification using a tried and true steel washer sticks to a energized coil method.
