Found the battery disconnect relay and it looks like the problem. Getting 12V to it, but nothing on the other side, even after triggering it manually with a battery. Covered by warranty but I'm not going to wait for it, so ordered a new one that should arrive early next week. So we'll see after replacing it.
In case anyone with a Outlaw 37RB is ever looking for the use/store relay -- mine was mounted to the side of a wood support behind the breaker box at the foot of the bed. Easy to get to by opening the storage "hatch" under the mattress and unscrewing one wooden panel. Also provided easy access to the backside of the main fuse panel as well as the Firefly panel.
