@stretchMike, I’m also in the PNW (Portland). Maybe we’ll have to get together sometime.
I got the hole cut for the hatch today. I’ll post photos after dinner. It looks like it’s going to be even better than I hoped. 😉
Regarding airflow, I’ll probably go with two mushroom vents on the rear of the trailer with some high quality PC case fans mounted inside, over the vents. The marine hatch has a setting where you can lock it open about 1/4 inch for airflow. We’ll see how that setup does. I don’t really ever camp in the rain, so I’m not too concerned on that front.
