Breakaway System

[Gayl R]

Could someone tell me where the battery for the breakaway system is located in a 2017 jayco journey outback. TIA

My Journey with single beds has it under the driver side bed, I imagine yours would be some where under the bed as well. It is only a small unit and does not look like a battery as it is inside a plastic case.

Looks like this box or a little bigger - depends on brand.
