So where does your dog sleep in your van ?

So..where does your dog sleep in your van ?  Our two wire haired fox terriers both, consecutively, decided the shower tray was as comfy a place as any.  This always worked well with their cushion unless you needed to go into end bathroom during the night when you were liable to get your toes nipped for disturbing sleep.  More difficult now - just bought fixed bed so no longer viable.  We now trust him to sleep at other end of the van with cushions all turned down to prevent jumping.
