? Winnebago Air Conditioner

Our former RV, a 35'Itasca Sunstar, had two 13,500 BTU roof a/c heat pumps. We NEVER had a heat issue not matter the outside temperature whether in the South Texas, Arizona or Georgia heat/humidity. I would keep both units on during the day and set at a comfortable 77 degrees. At night I would run only the bedroom a/c set at 73 degrees. We slept comfortably at night. Whether one or both ran they would cycle on and off per the thermostat setting. We always kept the windshield covered with an inexpensive sun shade. Our coach had MCI duo roller shades and thermopane windows. We kept the day sunscreen shades down. They did a credible job keeping the heat out while permitting the light in.
Prior to owning the MH we owned a 35' fifth wheel with one a/c. That a/c struggled in the heat but kept us cool at night. Nothing like the two heat pumps in the motorhome.
