New backup camera setup: Camera placement dilemma

Ours, on our 08 Monaco, has a power tilt. I can shine it out the back like a rear view mirror, or hit a button and shine it down at the toad hitch/ towbar.
Not helpful, sorry.

If the unit you bought doesn't have a power tilt, you can probably access the camera in the rear cap, and adjust or shim it so it shows you what you want/need to see
