On my Coachmen Clipper I am able to open the door when the roof is fully down. Is this normal? The roof latches are shortened as much as possible and fastened down tightly. I don't think I could get the roof any lower. There is a gap at the top of the door, allowing it to open. At first I thought this was normal, and I liked being able to load items for a trip without opening the roof. Now I am not so sure, I don't want moisture or bugs entering.
