The bed layout I have in my LWB MK6 is this......An "L" shaped seating area at the front of the van. The long seat running down the side on the drivers side with the L going with it's back to the front seats.
I have mad a 2 part slatted slider that interlocks with the long seat and pulls out to make the double bed. It is 6' long.
Next to the end of the bed on the drivers side is the wardrobe and then porta loo compartment for those little night time, caught short moments
On the other side is the Kitchen unit with sink & hob etc. I have a cabinet by the side door (You can never have too much storage)which I have hinged on the side to lift up a table.
I have privacy bonded windows, a roof vent, 240v hook up going to an RCD consumer dis unit.
Some put their beds width ways, but as you are tall like me, that is not practical.
