I do not have pictures, you put the pizza box in the main unit. The problem is the air from the fan blows straight down and very little air goes in the back ducted vents. Make the pizza box into a air diverter. Angle the box towards the back air duct and tape around the box to seal off the air. Now most of the air is going towards the back air vents. I also added an extra vent in the bunkhouse to improve air flow and a vent cushion to stop the heat from the vent. You will still get air to your quick cool vents, but no air to the front of the camper. Do you have two units? You have to run both units to cool off the camper after this mod. My camper's air works great after the mod and I was ready to take it back before the pizza box fix.
