I may have one of the few (it seems) where STORE means store... Completely off - coach lasts 1-2 months easily... And chassis battery has no issue either.
Been the case on both of my Thor MHs (first one had both a coach and chassis STORE - and both were absolute.)
If you do have a draw while in STORE - choices are trying to chase and find it; use a charger (on board converter or external), or add a hard disconnect at the batteries.
Quite often the batteries in a new coach are 'abused' on the dealer lot - left to drain down multiple times. Very hard on FLA batteries...
As suggested - get the batteries load tested, and replace if needed.
Decide which method you want to use to address any draw - so you don't kill the new batteries in short order.
