I believe that the rear seats in the SAR variant are different - as has already been stated the picture does not show a SAR variant, it is one of the prototypes in CG colours. The bulkhead is not there in the SAR variant and as Jeepys said, it will be very similar to the AW139.
Docs and maps will be in the centre console where the pilots can access them (not visible in the pic above).
I don't believe there would be anything stored on the floor.
