Disconnecting Battery When Plugged in for long periods

My batteries have remained connected for 11years.
No problem at all.
Systems are designed to have the batteries connected at all times.

Me too.

13.5 is really not that high for a wet-cell if you keep an eye on the water level. An AGM will be perfectly happy with that float voltage with no degradation whatsoever.

Of course, it depends partly on what exactly you consider a "long time" and how high the temperature actually is.

The battery also serves as a DC filter for your system. Should the DC from the converter have any ripple at all the battery will filter the ripple out making your DC pure. Also any spike from the converter that might harm any DC components in your rig will be filtered out saving $$$$$. I always leave my battery in the circuit.

If park power drops out and you're not there at the time your rig will be dead. If you leave the battery connected and shore power fails the trailer will automatically switch to battery power ... could make the difference between coming back to a fridge that's continuing to run normally (on gas and battery power to run the circuit board) OR quit running entirely and possibly losing all the contents of the fridge if you're gone long enough. Personally I leave the battery connected.

That is what I would do or at least keep checking the battery for fluid boiling out.

Of course the best you can do is replace your older converter/charger with a SMART MODE charger like the PD-9200 series is. Then you won't have to worry about the battery anymore... You most likely will only have to replace the charger module and hopefully can keep your same 120VAC and 12VDC Distribution Panel. Just replace the module in the bottom compartment.
