We have a 2003 Viking 1706 (bought used) and we can't get the door to latch consistently and it doesn't lock. Well, it locks but the lock doesn't hold because it doesn't go far enough over the frame. We think that the floor and roof may have been knocked off center. We bought a little latch like you see in bathrooms to keep it locked at night while we sleep (currently use a bungee). We need a solution for when we are gone during the day. Has anyone experienced this or have any ideas? Thank you!
