Draindown help

  I may have asked this before...my Elddis Odyssey 428 is in storage now, I've been down again today and crawled right around the van looking for the drain points.

  My wife followed me round, we must have looked a picture. The book refers to the 'external drain points' without saying where they are. I've asked on other forums, I've asked Elddis, who say 'they're at the back', Oh no they're not (I don't think).

   Someone on here must have one, surely??
