Won't "hurt" the battery, but will boil the electrolyte so you will need to constantly check and refill the water level. 13.6V will boil off water and if you fail to replenish it will boil the battery dry which is most likely what happened to your last battery.
If you are permanently setup and have zero intentions of ever moving the trailer you might consider just skipping a battery altogether as it is not needed in order for the WFCO converter to work. In this case the battery is more of a hassle and cost that isn't needed.
Modern converters do not need a battery to regulate and maintain 12V.
You will however be subject to having all 12V devices stop working whenever you have a commercial power outage, sort of like a sticks and bricks home..
If you might wish to move the trailer, of course you would need a battery to operate the emergency break away system..
You can of course disconnect the battery, but then you must remember to reconnect once every 3 to 6 months and allow the battery to fully recharge for a day.. Good chance you will eventually forget.
If you already have bought a replacement, you could see if they would take it back and get your money back if you do not plan to move it anytime soon..
