We also had a 23SS and had only one time when we just could not get it below 85 during the day, with PUGs and the A/C set about 75. Temps almost 100 degrees and humidity about 99% and not a shade tree to be found. We made a Walmart run thinking maybe an extra fan would move enough air, but no go. As soon as the sun went down, it cooled off quickly and was very comfortable. In almost 8 seasons, that was the only time, otherwise no problems. A bit of shade makes a huge difference.
