Hello everyone, I added the windshield sun screen today. I was a little nervous about drilling holes for the twist fasteners. It went well. I still have to add the side window sun screen. Sun Pro claims it will knock out 94% of the sunlight, heat and ads privacy during daylight hours. We should be able to enjoy the view out of the front. I am also hoping it will aid with the A/C unit to keep up on the hot days.
