Tender is word I know from cooking, but what it has to do with battery?
I used battery MAINTAINERS for my off-season toys and they do help a lot by having floating circuit who keeps 13.5V all the time.
But on couple occasions the maintainer failed and killed the battery, so they need to be monitor at least monthly.
So leaving battery disconnected up to 6 month turn out the best way.
Golf cart batteries hold the charge even after 13 months in dry storage.

Now that others have had their say I'll chime in with my own view I believe no one else has mentioned. ๐
During the season from April to Nov I park our trailer on the driveway here at the house and leave it plugged in 24/7. HOWEVER, I would not do this if the trailer's electrical system wasn't protected by an EMS w/surge protection such as the Progressive Industries EMS-HW30C I have. The reason - just as when camping irregularities in service power can and do occur, whether you know it or not, and can destroy costly electrical devices in the trailer, including the converter / charger. Right as this very moment my own EMS is displaying a PE4 error code, meaning a recent loss of ground which periodically seems to happen when there are power disruptions in the neighbourhood. In the years I've been protecting our rig with an EMS I've experienced low voltage that triggered the EMS and on one occasion one side of the incoming house source power going excessively high while the other side went excessively low, obviously a power distribution problem. The trailer in this case happened to be plugged into the side that went high so my EMS disconnected power to the trailer - had it not I'd have had some serious repair to deal with. All this being reality, I'd suggest that those not using an EMS only plug in as necessary to allow the converter / charger to restore the batteries, otherwise unplug and protect your trailer from incoming power line vagaries. If you do decide to ignore this advice then at least turn off all the breakers to everything but the converter so in a worst case situation only the converter may have to be replaced. Best solution though - invest in an EMS! :B

Also we just put new AGM batteries in.

Think about this? You plug in your camper when you are camping. Not uncommon to have it plugged in while camping for a couple weeks at a time, or even longer. Plug it in at home for several days in a row, or whatever. What's the difference between leaving it plugged in 2 weeks, or all the time?
