I see no reason why some simple cam locks would not work on all the
cabinets.  I can get them keyed alike through some of my suppliers, or can
rekey existing ones.  They can't be keyed to your existing Vanagon key,
however.  Installation would require drilling a 3/4" hole in the door of
each cabinet to be locked.  These are fairly simple locks, but do offer a
degree of security to the cabinets.  Remember, the doors and cabinets are
fairly thin wood, so if someone wants in, a screwdriver of prybar will pull
the door off regardless of the lock.  I've installed a similar lock on the
auxilliary battery compartment under the driver's seat to offer a locking
compartment.  The carpet covers it also.  Just an idea, but I don't see why
these locks wouldn't work.
