Loss of capacity means you get 11 volts when charging is complete. That's my interpretation at least. Sounds like you're beyond that point.
It could be a manufacturing defect allowed the glass mats to dry out and the battery is now toast.
If you dig around on YouTube there's videos on how to rehydrate an AGM battery... It involves drilling.
If you want to try rehabilitation, pull those batteries from the RV and work on them somewhere a rupture or explosion won't do much damage.
You'll need a beefy adjustable power supply like a Meanwell or Megawatt, a standard battery charger won't hit the voltage needed.
