When I first got my 6-volt T105's I watched them closely while connected to shore power. I found they overcharged even with my 3-stage converter. So I installed a disconnect switch and now when I plan on being on shore power for more than a couple days, I disconnect them. Everything still works just fine. And that is how my system works. Every system works a little bit different and to monitor your battery situation is always a good start.
Since the bulk charging specification of a T-105 is 14.8V, you must be having a converter malfunction to overcharge them.
Also, if a battery is left with no charge present, it is sulfating. It can be argued just how severe that is and what effect it has on batteries when intermittent charging is in place but it does remove some battery longevity (compared to the other situation,i.e. always having charge voltage present).
A drop in electrolyte level is customary and, if not excessive, does not mean batteries are being "overcharged".
