Excessive battery corrosion

Since I bought my Fleetwood Storm a little over three years ago, I've kept the batteries topped off with distilled water. They occasionally appear like they're low on water, but the level has never gotten so low that the plates are exposed. When I park it in storage, I hit the disconnect switch so they don't run down, and I only plug into shore power when at campgrounds with 30A hookups or when parked in my driveway (15A) when getting ready for a trip, probably 10-20 days a year.
Some more background: Last time I checked, the battery with corrosion read about 0.05 volts less than the other battery on my voltmeter, and my cheap hydrometer gave a slightly lower reading on one of the three cells. Also, I'm my Storm's power converter is a WFCO 55-amp model WF-9855.
What could be causing all this corrosion?
Too much water causes them to gassify and boil out acid. Use new nuts and then installed apply a liberal coverage of plain old VASOLINE and they wont get cruddy after you do.
Keep water at the proper level.
