[D&D Young]

I'm having the same issue in my 2018 Montana 3811ms. When I go to open/close my slides the system shuts down and resets itself. I notice the battery level at 13.6 when in start then drops into the 11's while there opening. Then the system resets and the battery level returns to 13.6 when it comes back on. This happens whether in pluged into a 50amp service or pluged into my truck. I can't believe my batteries could drop to 11 volts then recover to 13.6 in 10 seconds or so.
