Hi All, When we crank up the top on our (first) NTU pup, the tenting on the sides is super tight, which makes it difficult to open and close the zippered side windows - even to the point that the zippers start to pull apart. All of the bunk end windows are easy-peasy to open and close. The velcro attachment to the door frame is also super tight. The problem is that If we don't crank it up that far, the door will not latch into place at the top and will not open because it hits the edge of the roof. Is this normal?
