Right now it's 108F here in the desert and is expected to get to 113F later.
The A/C in the house is really expensive to operate so me and the wife went for a nice long ride in the C10. The factory A/c works amazingly well in this heat. I'm really impressed with a system that is over 40 years old and still cools as well as a newer vehicle. I have a classic Mustang that has a Classic Air unit installed in it but it just doesn't work as well in this kind of heat. It's also fun to see other classics on the road with all the windows down.
