condensation happens in hybrids more the popups, because they are more tightly sealed. popups will allow much more air circulation than a hybrid because of canvas walls vs. fiberglass walls.
this is discussed constantly on hybrid forums. you might want to do some reading in the Expandable/Hybrid section.
the main solution is allowing air movement cracking a vent and opening a bunk end window a bit. bunk end fans help also.
and installing PopupGizmos or solar blankets on top of the canvas ends helps a lot also.
