Coach battery draw

[Indianaduo]

Does anyone know if there's a draw on the coach batteries when they are switched on, not connected to shore power, and nothing is turned on? If I disconnect my shore power the coach batteries go dead in approximately 2 weeks.

Yes there is a draw. Co/propane dect. , radio mem. , maybe control panel if you have a remote. Little things that draw a little at a time.

Even if the disc. is off, still some draw.
