Hey Jack. Could you help me? I know you have a 2008 240Sundancer. I've got the 245 Sundancer which is the European Equivalent! Exactly the same as the 240DA I think. I saw one of your posts about how you having a macerator. I can't work out how to empty the holding tanks overboard. How do I do it? Is it something to do with turning the key next to the toilet? What are the two buttons above the key for as well?
