Is your main battery going dead in a week? Normally you should be able to leave the main battery connected for a week or more before there is a problem. But a lot also depends on the condition and age of your battery.
How are you charging your batteries overnight? Are you charging them by plugging into shore power? If so you need to leave it plugged in for a few days to be sure the batteries are fully charged. what is showing 100% charged? if it is the solar charge panel - it is meaningless as it merely shows the voltage on the batteries, not the true state of charge.
My 2013 Interstate does not have a battery disconnect by the sliding door so I can't help with that question. But it does sound like your batteries may be worn to the point where they won't hold a charge. How old are they? If originals they are likely no longer working properly.
