Living in Arizona, you use a/c year round. The a/c in this platform stinks! During the summer I was unable to cool the inside below 90 degrees! We have had it checked. I could drive 50 miles at 65 mph before the cabin started to cool down to the upper 80's. I was given several reasons why this was, but each service visit am told "it is cooling just fine" because they read the center vent with side vents closed and the air temp coming out, not what it feels like! Don't buy it!
