Batteries have quite a gurgle
I have this vision of small bubbles floating to the surface as the battery creates some gas while charging. Mine seem to produce a large gurgle. It would seem a lot of gas is trapped and then makes i...

Bubbling/gurgling seems exactly like what I think all liquid batteries do when their electrolyte is getting exposed to high "boost" voltages or getting "conditioned" by even higher voltages from multi-stage chargers.
This is probably not possible with either your RV's built-in charger or your solar charge controller, but if it is ... I'd recommend merely setting it's highest voltage at a lower value to stop the bubbling/gurgling. The reduced high end voltage necessary to stop the sounds is also temperature dependent -> the reduced voltage value necessary to stop the bubbling/gurgling would have to be set lower in warm weather than the setting necessary to stop it in cold weather. I expect that the high end charger voltages necessary for boosting or conditioning should also be reduced as a battery ages.
P.S. When your batteries are making sounds like this they're also emitting more corrosive fumes out of the caps, which of course is hard on equipment close to them.
