The new freighliners have no AC vent in the top bunk. I cant believe they left this out. All the heat from the day collects up top. My wife sleeps up there and unless I have the AC on full blast she roasts up and I freeze like a cold slab of lard in a meat locker in the bottom bunk Guess we will head to Walmart and buy some tubing and pipe it upstairs from the bottom bunk vent. This is a major design flaw in the new freighliners. Anyone else have this problem, any suggestions?
