It is strange that there is a filter/dryer for the rear 6-pack and not for the front 6-pack. And there didn't seem to be any difference in the rate of problems front to back. However, once I took it out I had new problems with the rear suspension. Coincidence? Beats me. But I have wondered if it's possible that its function isn't more as a filter than a drier.

Since I changed to the desiccant type drier for the overall coach air system I have not found water anywhere so I doubt water is a problem to worry about. That does not preclude dirt remaining a potential problem and if it is then an inline filter of some kind that doesn't carry the leak risks of the dryer type gadget would be worth considering. If I were to install one at the rear 6-pack it would make sense to install one up front as well.
