Keeping it cool when It is 100 Plus
A AC if working properly will cool the incoming air by 20 degrees. In other words if the temperature in RV is 100 degrees the air coming out should be 80 degrees. Some tricks to keeping cool in an RV...

Too late if it's already 100 plus degrees. The answer to your question is to prepare when it's much lower temps and be ready for the high heat. It of course, begins with the structure you are in and the true insulation and color of the exterior roof and sidewalls. The whiter (cleaner), the better! A reflective foil bubble sandwich layer in the roof near the top is a big help. Parking in the shade is a huge helper also or under a white canopy top type cover with adequate air space between the canopy and the roof for air flow. Sealing all cracks and voids in the RV helps. White shades pulled or reflective foil on the inside of the sunside windows helps a lot. A/C units have their limits and you can do so much to make them work less and be far more efficient. Of course drinking lots of water is basic and so is going away to an area that doesn't have such high heat issues as that solves all the 100+ degree issues automatically.
Dropping 20 degrees from the outside ambient air temp alone can easily be the difference between being comfortable and heat stroke death. After all, it's only your life you're dealing with! The long term effects to the human body from being extremely overheated can be devastating!
Being an engineer, I've never understood the reasoning for dark full body paint on and RV if it going to be used in high sun levels and hot climates. Like putting an ice cube on a black or dark surface under the bright sun and seeing how quickly it becomes a puddle of water. Do the vary same thing at the same time next to the dark surface cube but put the same size cube on a bright white surface and you'll see the difference before all thats is left is the two puddles. It needs no further explanation as your own eyes witnessed it!
