I've found a way to minimize or at least temporarily halt gurgling (moisture) problems while smoking. Once you start to hear and feel that gargling sound, send a couple of judicious puffs down the stem. This seems to work best on bent pipes, and pushes the offending moisture down into the bottom of the bowl, where hopefully it will become vaporized as smoke. Follow up with a light tamping. Using this method I've usually (but not always) been able to finish my smoke in silence and dryness.
