if you are stuck the percy arms at Armin near Goole will let you park all hard standing and they have a few manholes you can lift just ask for mike and tell him bill sent youWOw, calm down everyone
The last thing I would do ANYWHERE is dump my black waste other than in the proper place.
Just FYI it is 95 litre black tank from a Dometic macerator toilet e with chemicals. All sorted. Will dump when I get to Rawcliffe caravan park.
As for York, my daughter has been flooded out of her house and now in a holiday let. You do not appreciate what this is like until you experience it first hand and spend your Boxing Day rescuing precious personal items and seeing others lost forever.
