Is the roof air scoop functional?
Understand I am basically a new motor home owner, so this might seem like a dumb question, but I think the only dumb question is the one that didn't get asked.
My question is about the supposed rear air scoop on my 2000 Monaco Diplomat. When I tried to run a video cable for my rear facing camera, I thought I might be able to access a run down the air scoop into the engine compartment, and then on to the front of the motor home. I have an electricians metal fish tape and began pushing it through the metal grate up on the roof, but to no avail. It seemed that I could find a way into the compartment, the air cleaner, etc..
Now, comes my questions:
Where does this duct go, if anywhere?
Can I seal that up and endanger engine performance?
I'm having a rain leak problem in the very back of the motor home. I've tried sealing up everything on the roof, along the roof rails, at all the side panel seams, and also replaced the slide seal back there. It's not as bad, but still gets wet, and I'm wondering if it's leaking somehow through that fresh air duct.
Positive suggestions are appreciated. Wise a** remarks will be ignored.
