Well, you inspired me to answer my own question. Here’s the manual

Now I know where the cameras are. That’s pretty good coverage. The reverse camera is on the tailgate. If it is lowered, the camera is unusable. However, there is a cabin camera that is rear facing. That may provide some coverage to the rear, but might be obscured by things inside. Appears to mostly be for watching the driver’s eyes for inattentiveness, so I don’t know where it is aimed.
