One hassle with shore power charging is long term overcharging.

The unit does fine , then an accessory , DC fridge or furnace switches on.

The voltage drop is enough to have the charger decide a full charge cycle is required.

Sadly many of these top out at 14,4v and switch to 13.4 to .8 to float.

This slight overcharge eats water , which can kill the batt.

Simple is HydroCaps which convert the gas back to water.

Simpler is to lower the charge voltage top and float settings , as all you really need is a bit above 12.6 or .8 to keep the batts happy all the sitting time.

With no power hose we use solar year round and simply set the V regulator to a lower float.
