3010DS battery drain

[kins83]

I have a 2016 3010DS. There seems to be some parasitic current drain on the coach batteries. Even when I turn the battery cutoff switch off, the batteries will run down in a few weeks of storage. I'm thinking about putting in a knife style cuttoff switch at the battery. I'm wondering if the leveler jack control board is what's staying powered on. If that's the case then if I put in the cutoff will the ignition interlock for jack down still work if I forgot to reconnect the battery. Does anybody know what might be causing the drain? Is the leveler control connected to the coach battery around the switch? How does the interlock work.

The Jacks are wired direct to the battery. They are always powered regardless of the disconnect switch.
