The signage in question is misleading. Coming from the direction of Herbsthausen, there is a large sign in front of the bridge indicating P cars/buses/motorhomes (symbols) to the right, while a smaller sign on the signpost behind it directs to the motorhome parking area to the left. Booking and payment can be made through their paid app. The fee is €5 according to the notice, and a city tax of €1.90 per person can be paid at the Tourist Information in Bad Mergentheim. It's unfortunate.
