On our last trip the lock/latch broke and won't keep the door sealed that well. I haven't had a chance to really look at it closely but we are taking it out this weekend and will check it out then. It seems that the front cover of the door can some how slide off or be removed to give acces to the lock and try to repair it but I'm not sure. Has anyone in the past had this problem? How did you fix it? Thanks!
