Condensation in a new Ventura Atlantic awning

We have used awnings for approx 40 years last year we purchased a new Isabella Magnum with NO condensation problems. We decided to purchase a full awning Ventura Atlantic we were amazed by the amount of condensation on the inside of the roof. We do not cook or sleep in the awning, it was vented and on the last two days the caravan skirt was removed. If the roof was tapped droplets of water came down, there was no condensation on the fibreglass poles or on the sides of the roof. Has anyone else had this problem or has anyone any ideas how to cure this?
