Ideas for keeping a P3 cool during hot days?

I tooled around Phoenix & Tucson with mine in my Tradcraft case with no issues whatsoever. If shade is an option +100 for that.

I really don't think you need to worry. If the whole car cooks off at 135F that would be bad but I bet it will be closer to <100F. Here in Colorado, because we are all so High, it is lucky to hit 80F in your car.
