Actually if the trailer never moves you probably do not even need a battery.
Maybe, maybe not. Slides and awnings are intended to be powered by the battery but some, my awning & small sofa slide being examples,
will extend / retract just fine without a battery and with just the converter providing power to these devices. If the OP's trailer has a slide and / or awning he could try extending / retracting them without his battery connected - if they work then there's no need for a battery at all on his permanently situated trailer. If they don't then he knows he
needs a battery and should disconnect it whenever he's not actually using the trailer.
