VW campervan with original hard top

This VW campervan from Mercus has a very original roof to it I have never seen one like this before. This VW campervan has no shower but the company tells me that they want to add this in future models there is space for it albeit, not a lot. Mercus manufactures in Poland and are distributed in Germany. I live in a motorhome full time and travel around Europe in it. I spend most of my time in Poland, Germany and Italy. Vanlife is my life.
