This is not model specific, but twice I have cut holes in my camper and found a 120 volt AC wire running through the area. When I cut for my dryer vent, there was no mark. However, I know I was in the same area that the factory cut and probably within an inch or two of the proper location. I carefully cut the inside hole first and found a wire right there. Fortunately, there was enough slack to move it aside. Also, I installed the duct from my microwave to outside so I could exhaust cooking smoke, etc. Again, there was the wire. This one was the one to power the microwave. Again, why did they put it there? Crazy, huh?
