This is the basic layout - the seating for the "office" is on the bed mattress which is custom built with that corner missing. There are plenty of flat spots for coffee mugs and stuff and lots of little storage nooks that are handy for torches, mobile phones etc. Some of these nooks have a door but most don't. There is a storage area next to the entrance step for shoes.
We expect most of the sleeping will be done in the fold down bed but when it is very hot\rainy\windy the lounge will make up into a large bed.
The floor is flat with a one step outside the toilet\shower that houses the "house" batteries and another step for storage and making easier access to the fold down bed. The bathroom floor sits over a 180 litre drinking water tank and there is a large storage area accessed from outside under the step and wardrobe.
The windows and vents are all fitted with midge proof screening and the lounge windows are supported by gas struts to open to almost a horizontal position to assist in airflow. The small window over the sink and stove is fixed and the louvre window in the bathroom winds out. There is a 4 seasons hatch in the bathroom and a large hatch in the centre of the vehicle that doubles as an emergency exit\access to the roof. Four solar powered vents suck hot air from near the ceiling and vent it outside. They can be closed when required.
The roll out awning fits into a recess when not in use.
