The last photo, shows my answer to the bed problem!
Its a drop down bed!
In the day time it will be lifted by an electric motor up to roof height, high enough to walk under, and then in the evening lowered to a top of mattress height of 750 mm and will have a standard domestic mattress, so nice and comfortable, and you can leave the bed made up.
It lowers onto the area where the sofa`s are, so you have the benefit of a fixed double bed, without using up all the space or having a larger vehicle.
You can also stop the bed at half height if you want, that way it makes it 4 berth, with the sofa`s made up to a bed underneath.
There is a clever built in micro switch that you can set so that on pressing and holding the raise or lower button it will automatically stop at you preset positions.
It was a nightmare trying to obtain the bed, as it came from Italy and had to be made to my specification, (I don`t speak Italian!!)
It took six months before I received it. But it was well worth it.
