Battery drain, 2009 Sundance

[eieioh]

Buddy has a 2009 Sundance that is draining the battery (single) in storage. Is there a known problem? Is there a disconnect switch?

Thanks.

There maybe a battery cut off switch in the display panel on TT or 5TH. If kept in storage for any length of time would remove batteries and store at home and full charge them before reuse.
You have circuit boards, fridge, radio, furnace, WH that may draw battery down over time.
