That's what I thought too.  The passenger side electric refrigerator is being referred to as an ice box.  I can't imagine dumping a bag of ice into the jump seat compartment.

cooler box under the driver's side jump seat. It went for BIG dollars
when I sold the parts off. It slid into the base of the seat, with its
own 12V plug and socket there.

The window sticker from my 85 Westy Wolfsburg states
"Removable 110/12 Volt Ice Box"
"Cushioned seat behind drivers seat with underseat storage"
The "ice box" is the dometic 110/12V cooler box that attached to the floor
behind the front passenger seat.
