Will it be have a sun protective cover over it or exposed naked to the elements?
In parts of AZ, interior temps with no a/c can easily reach over 125 degrees inside during the summer. You need a cover or at least window sunshields. I have seen sunbirds come back in fall to exploded containers of food everywhere. It's not just how hot it may get but how long that sustained heat is present. Each year all the news stations do their annual fry and egg on the hood or place a block of ice inside a vehicle to show how fast temperatures rise. One did an RV and the temps were over 125 from about 9 in the morning to 9 at night. I don't care how well an RV is built, that is some serious high temps to endure almost every day for three months. Imagine whats happening to any food or drink!
