You're in the same heat bubble we're suffering from. As I write, we're at 111 Degrees F at 6:55 PM MST Sunday. We're edging into a potential 120 Degree Tuesday. If it doesn't make it to 120, who cares? I'm already done on this side Really awkward to say, but that's the best time to test the A/C - when things are at or very near their worst. Now you know for future reference. The factory tint on a window wagon doesn't stand up really well against a climate that tests the limits. I have a very, very old minivan with clear windows, factory tint on the windshield only, and yet live in the Phoenix, Arizona area - the dry heat capital. Anyway, the windows round the van work against the A/C. Did you test it with rear A/C working simultaneous? If so and you weren't impressed, that could be quite a negative ding right there. Since I don't work with my hand-held, but for Texting or emergency calling, CarPlay or Android is not relatable, so I'll hold off there. Low-end to Moderate window tint - an aftermarket further cost - could, maybe, possibly, help the effectiveness of the A/C; but it's your money/payment and you have to feel confident of your choice. Definitely thank you for the review. Include anything else that comes to mind you think might help round-out the picture.
