I'm going to be in Kaiserslautern next month with an RV but all of the camp sites are booked because of the world cup. Can anyone suggest safe places to park an RV for 24-48 hrs thats not too far from the central area? I dont need access to water etc. Addresses or area codes would particularly help as I can put this into my sat nav and so I can find my way back to the vehicle at night! Many Thanks
