Vents for portable AC and CT windows

[BKP]

about to start collecting all the parts for my trailer build and wondering how you're doing a vent for portable AC/heater and what windows you like for cargo trailer installation?

I used 4" marine deck plates. Frankly the portable AC units do not work all that well at dehumidifying and this is a lot less expensive. The write up and what others have done with that idea is on the forum.
