Was the battery ever run low on water?... below the plates?
Was the battery ever allowed to go below 10.5 volts?
These are two of the biggest battery killers.
The water levels have always been good. I have not seen the the voltage drop that low while I have camped with my parents off the shore power.

Are the batteries removed or disconnected while the trailer is stored or is power available 24/7/365?
Most owners of solar battery tenders have a very small panel, usually under 20 Watts. Those small modules may not keep batteries charged if there is any load on the batteries.
Really not enough information to make an exact diagnosis but, all things considered, it sounds like the batteries may have sulphated from not being charged correctly.
Has anyone checked electrolyte levels, put a meter on them, or done an equalization charge?
The batteries are only disconnected from the trailer (not the solar) when in storage at home. And the little charger is like 18 watts. And we have put a load tester on them and they tested fine, but we have not tested the electrolytes.

Without voltage readings and machinery model numbers this one is pure guesswork.
I will see about getting the model next time we're up there.
