We added a secondary slider about 4" long which is at about 60 degrees
to the main slider and an inch or so aft.  This piece takes the load
only during the first few inches of deployment.  It opens the door
slightly sooner when the wheel is coming out and avoids having a side
load on the main slider.  We found that the main slider height could not
be set to both open the door soon enough and allow the door to close
completely.
