I have an Outwell Montana 6 and a kids room. We originally had the 2009 Montana from Go Outdoors but there was a cut in the fabric so we took it back and they gave us a 2010 model in exchange. We bought the kids room at the same time from a different supplier (online) but it is still in the box because my DD was too young at the time but I wanted to get it at the same time as the tent. I've just had a look at the kids room online and there's now a message on a website selling them that they don't fit the 2010 and 2011 Montanas. Does anyone know why it doesn't fit the 2010 model and can it be bodged????
