Your diagnostics quite frankly are at best convoluted. Any, even brand new battery of high CCA design that "goes flat" gets damaged. Irreparably so.
Voltage when used by itself is the mere faintest of hints as to the health and potential lifespan of a battery. Sort of like "His temperature is normal, therefore he cannot be having a heart attack".
I really do endorse the idea of constant charge maintenance (temperature corrected float) on BOTH the house and chassis batteries. If you have a brand new rig that throws a hissy-fit if the ECU loses power then you cannot chop power with a switch. But if your rig can handle a power chop, the CHOP IT. What's the use of risking an unwanted, unneeded load? Leaving power connected when it is unnecessary would be like going on vacation in the summer and returning to a surprise 5,000 kWh power bill.
