How to cool the v-berth area? The small Frigidaire AC is place into the center opening window. I then made a funnel cover that fits over 1 side of the AC. It literally snaps on using 2 magnets. Holds fine and I then slide on the hose that runs into the v-berth. The air blows in quite strong and nicely cools down the forward cabin while the other side of the AC unit is still cooling the main cabin.
