better out then in as they say

I would have two bench seats at the rear, one each side and a roll of slats or pull-out to form a double sleeping across the van.
You will then have space to get at sink, fridge and cooker with bed made and have all gas appliances together, fridge under cooker and cupboard under sink preferably on nearside.
Lengthwise lockers above seats, offside one joining onto washroom behind driver with a 3 drawer unit with a slide-out/clip-on table beneath it between bench side and washroom side, with baby cot on top of drawer unit/table.
Dunno how much floorspace you've got but here's my amby which may yield some ideas.
