Floor plan

Explanation of floor plan
Here's a sketch of what we plan will happen... The second pic is a sketch is based on our 6 m long body. I saw the single bed idea in another truck (first attached picture. Whoever owns this truck, I love your plan and hope you don't mind me basing ours around yours!), and we both like the idea of single beds which lessens partner disturbance when getting in and out. It also allows for a Queen size bed when sleeping across if required. The bed area is raised with outdoor lockers underneath and a space for the genset in the middle. The composting toilet and basin will be in a room of their own, as will be the shower. The doors to these rooms also allow for closing the bedroom and privacy. The seating area will be raised by approx 400mm allowing for batteries and water tanks etc. All yet to be planned. There will be a central floor hatch and between the chassis rails we will house the heating etc. The third pic is of haw the cutout will look. Any ideas or suggestions welcome.
