Yes, the storage area can be accessed while the tent is opened. Like you, I try to keep an organized camp, and if it is in the trailer, I don't have to go looking anywhere else. In fact, it is easier now to get into the trailer with the tent opened up than when it is closed. With the trailer all set in road mode, it take significant effort to start the lid moving upward. More than 50# of effort. I am going to have to rethink the placement of the struts. They are too near horizontal when the lid is closed to give any assistance.
