Mounting a window in 3/4 plywood

I've recently got a couple of Grant's wonderful little windows for my teardrop that's eternally under construction.
I'm want to put them in the doors of my trailer, and these doors are made from 3/4 plywood (no sandwiching).
However, I can't figure out how I'd mount these once I cut the hole out. It came with a bit of trim, but the trim seems to work for a wall about 1 1/2" wide. Does anybody have any pictures of how it's done?
Thanks,
Lance
