The typical A/C will have a temperature of differential of 20 degrees Fahrenheit. That is the exit temperature should be 20 degrees below the inlet temperature. More than that and you risk the evaporator coils icing up. The problem is full sun on the coach and the huge glass windshield. If you cover just the windshield with a product like Reflectix, you can remain cooler. About the max temperature differential you can expect in a class A coach with single pane windows and uncovered windshield, in the full sun is 16-18 degrees. I find that in the Texas heat if we run both roof A/c and the dash air we can travel comfortable. If we are parked for the day, we try to find a shady spot and install the Magne Shade. It is 96 in West San Antonio today.
