Cool Double or Triple...An AC Question

Most of the heat will come from the front windshield and the front and rear caps. I have insulated all of my windows and roof vents with Reflectix Insulation (reflective bubble insulation) and that includes the shower bubble. It reflects 95% of the radiant heat. I get the big roll and cut it to fit all windows, including the driver/passenger windows AND the front windshield. I put it between the day/night shades and the window glass. It's dark in there but I can easily remove one from a window and roll it up for quick reinstall if I want. I have also insulated my front and rear caps. I'm good in 110+ Texas heat. I also keep a 3 speed fan in the bedroom doorway to circulate the air (it rotates either direction). I usually just run one a/c at night and if I've got a shade, only one in the day time (front a/c at night with fan pointing at the bed or the rear a/c in the day with fan pointed toward living area.)

Both of my a/c's are the 13,500 units.
