How do you feel about the canopy tents with regard to heat?

Also can we get like a camping tent thread to discuss and maybe poll for tents that would be cool. IDK how to do it but would love to help.

But yeah the canopy tents. I have one, I like it over the truck tent sans canopy I had my first roo but idk if it does the greatest job at cooling, what's the best way to stay cool?
