Bill-
Henderson's found a cracked fitting, but fixing that didn't do the trick. BCS found a bad air horn connection, but the red needle still tanks overnight. Don't know where this leak is, but it's not making itself obvious and is costing some in the labor dept.
I have noticed that the back of the coach doesn't seem to go down when air leveling, or when I dump air; hard to ascertain as I can't hold the dump button and watch the back end, and potential helpers so far are always busy. On leveling, the front is inevitably low on sites I've been to so far, and it airs up in lieu of the back dumping. When I deliberately (manually as opposed to auto-level) try dumping the rear, I get a repeated psst, psst, psst, psst rather than the usual steady air release. No one that's heard it so far has explained it, which is a bit discouraging since the sound I'd expect to be revealing to someone in the know. Hate to think I have to travel back to HWH to resolve it. At least it levels and seems to stay there for awhile.
Whether this has anything to do with the air loss from the secondary tank, I have no clue.
