Google Images '189 SAR' and you'll see the proposal for role equipment and stretcher stowage. Best of luck with that. You'd have more luck putting four elephants into a mini than getting this lot
first response bag, the second response bag, the casualty monitoring system, the defibrillator, the crew's kit bags, the paediatric bag, the smokes, the hi-lines, the life jackets, the chocks, the NVGs, the aircraft documents, the maps, the camera, the medical gloves, the torches (small and large), the spare oxygen, the entonox, the thermal blankets, the body bags, the winching kit, the restraint equipment, the spare winching kit, the rescue strops, the child rescue valise, the splints, the KED and two stretchers

The cupboard looks about the size of an armchair and is blocked by two seats. Where do you put those when you need access? Or the people sitting in them?
Docs and maps will be in the centre console where the pilots can access them (not visible in the pic above).
What, all the 1:50,000 and 1:250,000 for the entire region that you may get scrambled to? That's a big centre console. Perhaps they can store some of the medical kit in it too.
Blind faith will only get you so far.
