The “duct” is most often just a track that is cut out of the solid insulation (styrofoam) and is often run the length of the coach. If you have a good inspection mirror I would simply take the vent out in the bathroom and look for the ducting.

If it’s there, then some careful measuring and a hole saw will work. Other than that, I would be Leary of putting a vent in the wall, without checking for wiring or plumbing.
