I assume this also translates to an ability to keep cool in hot climates.
I would not make that assumption.
Of course it depends upon your definition of a hot climate.
It will take two ACs to be comfortable in parts of Texas, Oklahoma, Arkansas, Kansas in the summer - when the temps are near 100.
Even if the ACs are cooling properly, if you are in southeast Texas or Louisiana, Mississippi, Alabama - the humidity will be so high that you will be feeling clammy and sticky inside the trailer.
Like many people in the Dallas area - late June, July and August are my least active camping months. It's no fun to go somewhere and have to sit inside 22 hours a day because it is too hot to be outside.
Windows are the biggest problem with cooling. The fewer, the better. Our new 35' Flagstaff trailer has 15 windows along with three overhead vents (and two ducted ACs - on 15K the other 13.5K).
Among the first things I did after picking it was to measure and cut insulated silver covers for each of them. When we camp in the summer - the covers stay on the windows on the south and west side of the trailer during the day.
