Am trying to find a second hand annex to fit my Dorema Calypso, I'm not tight but just haven't got almost £200 to spend on a new one. On a couple of occasions this week kind people have offered their annexes at good prices. I checked with Dorema and they advised that the annex from a Sirocco or a Country will not fit a calypso, indeed as you may have guessed only a Calypso annex will fit a Calypso awning, but there is a bonus, so will a Madison annex...not as straight forward as it seems , but what is !
