I think it is pretty much the same canvas as a popup. At least is is on my Jayco compared to my previous popups. My guess on the condensation is this - Since there is so little canvas compared to a popup, the small amount of canvas that's there is is a big temperature difference compared to the rest of the trailer.
I've only ever had condensation worth mentioning once in my hybrid. That was this past Memorial weekend when it was really cold and wet outside and we had heat running a lot more than ever in the past.
