I read that being on shore power for too long damages the batteries, would it be a good practice to disconnect the battery circuit when I am plugged into a power post?
For over the winter storage I have a trickle charger on the chassis battery and a Battery Minder on my coach battery. For other times, The converter, a modern 3 stage converter (PD9260) keeps the battery charged without boiling the battery. I monitor the battery water level and add distilled water as necessary. It is plugged in all the time, unless I am camping with no hookups.
