member lp24, two green stars [Online] Posted 15 July 2013 by lp24 Quote | Report The door flyscreen on our Lunar Ariva is useless. It's a rollerblind system which is difficult to fasten open from the inside and impossible to operate at all from the outside. I was considering replacing it with the concertina blind type I've seen on my sister-in-laws Bailey caravan but I can't seem to find any online. Does anyone know where we can buy a replacement concertina type flyscreen? Post liked!
