so im trying to list all the things different about the '91 westys that
were different from the earlier westys...so far i have:

-left rear cabinet front door is shorter to allow front clothes closet door
 to open without moving stowed table
-rear hatch has inside finger latch to open from inside van
-front headliner has added support bracket so it wont sag in middle
-inverter box redesigned in cabinet under water tank
-

what else?   there are other differences...feel free to  add..
