Electric window trick:

     It did NOT work on my '91

     Insurance of Westfalia stove, fridge, etc:

     In my case, anything that is "part of the car" is covered; anything
     that is not is personal property coverd by my homeowner's insurance.

     How "anal" insurance companies can be about this distinction became
     very clear to me several years ago.  I had a camera bag "lifted" at
     the Philadelphia airport (like the license plate used to say, "You
     have a Friend in Pennsylvania").  My keys were also inside.
     Homeowner's insurance covered the camera, and every key on the key
     ring except the car keys; they were considered "part of the car".
