battery charger?
Today, the battery voltage is dropping. The RV is plugged in and the 120v Christmas lights are on. I dont think i hear the normal hum/buzz of the battery charger...

Check the battery for fluid level, excess heat or 'boiling'.
Assuming the battery looks fine, disconnect one cable and check voltage of the 12v system and check battery voltage after a few hours or next day.
Post the results.
