Jon M, What a very kind offer, don't worry I won't turn up on your doorstep to take you up on it. I am going to K.H. on Friday to have a chat, Dan White is going to be there, in the meantime, I have found a use for a spare Air Wedge that I have, it has been re purposed as an inflatable lumber support so it will be interesting if that helps at all.
