I have a 2012 Berkshire with the factory installed Dometic AC units on the roof. My coach has never seemed to cool properly. Has anyone had similar experiences. The coach with not cool at 88 degrees outside temp., it does not touch the heat at the river..
yes, even with the 15,000btu unit up front, people are reporting that the super large windshield still needs to be insulated to get the coach cooled. without some type of insulation on that windshield, forgetaboutit...

I felt mine would not cool properly either. The windshield is like a big greenhouse, so I went to Home Depot and bought a roll of foil insulation and Velcro. I placed Velcro strips along the top of the inside of the windshield and cut a piece of insulation to fit. It worked out well because the roll is 4 feet wide and I didn't need to trim that.
