We stopped here after business hours looking for water. It's hard to find, but there is a service setup on the backside along Weiherstrasse. It hard to get to though because it's up against the building and they park their vans on either side of it. With a long hose it was possible. Also seemed that there were no places to stay overnight since they use these places for their own vans too.

We drove here on a Sunday but no real Stellplatz although there was a sign in their car park but only campers of the dealer were actually parked there, couldn’t find any dedicated parking otherwise, good camper shop there which we went back to on Monday as closed Sunday! Also service centre if needed.
