Got it. Someone on TNTTT had sketched up a drawing of a window unit under the bed on the floor that had a floor panel that dropped down when stopped which exposed the AC coils as needed. It was actually very creative. If you are making a permanent bed built off the floor, let me know and I'll dig around to find a link for you. No holes anywhere except a drop down panel underneath the trailer. I could see that working under a sink or fridge cabinet or basically underneath something that would take up floorspace anyhow.
