Chuck, Suggest you look at a larger outlet grill for the cabin. But use a wye with an adjustment on the discharge of the AC. That way you can direct more air to the cabin or aft berth as needed. There will be times when you want a lot more cooling in the cabin than the aft berth. If you're using the round directional vents with shut off in the V-berth and aft berth, you can close them off to help direct more air to the cabin but the adjustable wye will help adjust the air flow overall.
You'll only be using the berths at night after the sun goes down. You'll really want lots of cooling in the main cabin during the day and evening. Especially if you're cooking. Dennis C.
