We went to a pop up for about 2 years, with the rooftop ac. It keep the camper cool. If I was parked is the sun I would use the pop up gizmos, and considered getting the silver insulation from Home Depot to put in the windows around the beds in the middle of the summer. We went we went from a 30’ 5er to a pop up. I liked how easy it was to pull and the wife loved all the windows, but hated how long it took to set up and always worried about rain when we showed up or left. I finally talked the wife into returning to a 5er this year and won’t look back.
