That rear bathroom and the tall, wide but shallow garage between it and the rear doors I think is a great idea and just how I planned to do my next conversion if I did one.
Paintwork is easily fixed with a roller job given it is an old van
I have no need for one myself, but if I was after a 'starter' van or wanted to dip my toe in the water to see if a campervan was something I would like or use, that sounds like it could be very good
