I just leave them plugged in year round with a good charging unit in the rv.
And risk the charging unit failing & perhaps failing & overcharging the battery bank, trashing the batteries? No thanks.
If the unit is stored at home where you keep a constant eye on it then fine, leave it on if it makes you feel better. If it is stored remotely where you don't get to it for weeks, months even, better to disconnect & leave the unit completely dead for storage.
No risk of the charger failing that way.
I get to see my unit for the first time since last October in three weeks time. It has been stored completely dead since then. With the exception of a little self discharging over winter, I expect the battery bank to be just fine & will be 100% in a half hour or so of power being restored to it.
Much is made of leaving batteries on trickle chargers by RVers, but look around. Farmers leave equipment for months without use, no chargers. Boaters leave boats on moorings for months unused, no chargers. Construction equipment sits unused for months, no chargers. All kinds of other vehicles sit for months in lots unused. No chargers.
RVs can certainly do the same.
