How does the air flow through a 4kw Onan in a 23' GMC?

How far back from the door is the power drawer supposed to sit to allow enough air through the grill?

Where does the air come in and where does it go out?

In this picture, you can see that the only hole, other than the grill in the door, is the bottom of the compartment. The power drawer mostly covers the hole. Doesn't look very conducive to cooling.

I am working on putting the Onan back in the gen compartment, and I don't have the OEM frame bracket. When I get a bracket that will bolt in, I need to position the drawer on it and then mark/drill the holes. I want to make sure the airflow is at least as good as original.

And while I have your attention, what did they make the original enclosure out of? All I have between the living space and the gen compartment of the Sequoia is 1/2" plywood.
