Based on my experience with my '85 Westy, there ain't no good
arrangement of rear table and door, a problem cured in later models
(like my '90).  Later models (as noted by several people on the list)
have a shorter door, it clears with the rear table swung in over the
storage compartments above the water tank, but only if the table is all
the way down.  The modification (cutting the bottom off the door and
gluing it in place in the bottom of the opening) seems like an elegant
solution, and I sure would have done it to my '85 if I'd had the brains
to think of it.  As far as the rear table swinging out during travel, I
added a small hook-and-eye at the left rear (as facing it) of the table
top, screwed into the outer wall and the edge of the table. I used one
that had a spring loaded retainer on it and it never popped loose.
Worked great to hold the table in place.  So far I don't seem to need it
on the '90, go figure. BTW, I have found that leaving the rear table
swung into it's storage position but raising it about a foot or so, held
by the locking screw, allows the lids on the storage space below to be
left open and gives additional storage on top of the table while camped,
food, dishes, etc. kept in a plastic storage bin.  When traveling, lid
goes on the plastic storage box, bungee wrapped around it and the table.
Drawback:  with the lids up on the storage, the table still sticks our
just enough to make it a problem to pull out the bed.
