A month or two with loads disconnected should not be a problem for AGM. Just make sure you do disconnect them - no fridge running, no radio on standby, nothing. At 68F AGM have very low self-discharge current, typically 3% of initial charge a month. When it's really hot, like 104F day and night, 24/7, then self discharge increases to 10-12% a month so it will take 2 months to drop to 75% - still no need to maintain. Though I doubt there is ay place in the US that can be that hot for that long.
Interesting! Whom is the manufacturer and what model?
