Mystery Relay Draining House Battery

[HappyCamperBob]

Hello all! Does anybody know what this relay controls in my 2019 5255? This is the culprit that keeps draining my house battery in about a week when the coach is not in use. This panel is located right behind the house battery under the slide. This relay continuously draws about .25 amps which eventually drains the battery. I've checked that everything is turned off in the coach and the main battery disconnect switch is off, and the relay still draws power. Any help would be greatly appreciated. Thanks!​

On my 2006 super c, the emergency brake has to be set to extend the slide out.
With the emergency brake set, the relay is drawing power. So once the slide is out I have to release the parking brake.

Yep - that's exactly what the problem is with my coach. I'll be installing a switch which cuts the power to the relay so I can keep the emergency brake engaged when the coach is parked. Thanks!
