With the inverter/crock pot cooking under way conversation going elsewhere
here, it's probably a good time to bring up the Subject.
    Anything you have, unsecured, in your van as you're going somewhere, it
will become a potentially lethal projectile in the event of crash.  The
whole van and all it's  contents are full of kinetic energy at speed...stop
the van against something and all the loose  contents will keep going until
THEY get stopped, too.  If that crock pot, that set of golf clubs, that
portopotty, that table saw hits YOU or anyone else during a crash, it is
likely to damage or kill.
   One of the cardinal rules in auto racing and for club tracktime events
is absolutely no loose objects inside any car when on track.
   Yes, it's really not something we often consider as we VANAGON around,
but inertia exists.  Something to be aware of.
