Hiya, first post, thought I would give it a go. Ive been told ive got osteoarthritis in myb spine - now I know why my backs been aching in the mornings, I thought it was the alcohol !!! Anyway, unable to change the van at the moment to a fixed bed option (credit crunch and all that) we thought we would try and change the end bed on our 5 berth lunar to a fixed bed as we are usually on our own now. It seems as though it should be a fairly straight forward job, and OH is a bit of a 'handy andy', just wondered if anyone had done this before and put a proper mattress in place of the caravan cushions.
