A lot of it depends on if you can handle the heat.
Had two couples who lived in the park we go to, year round in travel trailers. Didn't run their A/C until it got over 100 degrees outside. Once it cooled off, which to them was under 100 degrees, said they were fine with a fan blowing on them.
Had another couple spent the summer in a MH with three A/C. Two that came with the MH and a portable one. Had insulation on the windows, under and the sides of the MH. Said it felt like they were living in a cave. Survived, but said never again.
One thing a lot of people say is they go out after sunset to do stuff. Just have to wear gloves when you go out to your vehicle. The handle, steering wheel and key starter can burn your hand(s).
We are in Arizona the end of September. Start out jobs October 1st. It's still well over 100 degrees. Both A/Cs run most of the time, plus a little portable fan we have blowing on us, keeps it comfortable enough. But then I'm not a fan of the heat. Can handle 40 degrees better then 100 degrees.
Again all depends on if you can handle the heat or not.
