I would put a sheet of paper on the outside wall, and use a good stud finder to find the aluminum rails beneath the outside wall before cutting into anything. Make marks on the paper on the wall where the stud finder finds a "stud" and it will find both studs, aluminum frame members and wires. Good stud finders use short range RF detectors to look into the wall.
Secondly, use a boroscope to verify what you think it the case and look around with the tiny camera on the end of a long flexible wire. I bought one on amazon that has replaced my USB based boroscope since it has a small display and two cameras.

If you get a boroscope, you can do an exploratory hole in the side wall and look around from outside but from the room you have under the RV, you should be able to see lots around the furnace.
I guess I'm lucky in my raptor, which has the furnace under the fridge accessible in the kitchen at floor level.
