Ditto what others have said. Our sales guy gave us the expectation that the a/c in the popup would give you about 10-15 degrees of coolness as compared to the outside air. I would say that ran just about right. If it was 100 outside, it'd be about 85 in the 'living' area of the camper, and a bit warmer than that in the tents.
When camping in hot weather, we would keep the curtains on the bunk ends closed during the day and that would really help keep the temp in the living area much cooler.
And yes, if you are napping in the bunks and the sun is a-shining, it does get pretty sweaty in there, even with the AC running...
One of my fav things about upgrading to the v-lite TT is I have actual airconditioning vents IN my bedroom and can take a really nice, cool nap! I don't miss the tent 'greenhouse effect' bunk ends of the popup.
