Plugged in or Trickle Charger
Our trailer is now parked next to our house. I could keep it plugged in 24/7. Is it better to do that, or take the batteries out and plug them into Battery Tenders if the trailer isn't going to be use...

Upgrade the outlet to make it switched.
Add a trickle charger.
Find out the parasitic draw on the RV, and discharge rate of the battery bank. (depends on age, among other factors)
Add a timer and power the charger for one more hour per day than needed to cover parasitic losses.
I do this with my car when I snow bird for 4 months each year. The battery is OEM and from 2013.
What good is a switched outlet? Too hard to pull a cord out of an outlet?
And they make a replacement for trickle chargers and timers. They're called battery tenders.
Unless you like 20th century battery charging.
