Hi, I am thinking of buying an annexe for the expanda as we are going to the gold coast next April school holidays and staying in one caravan park for 10 days. I have never had the need for one yet because we have always been on the move and only staying a few nights in one place at a time.I have seen prices of canvess ones and are a bit out of my price range but have seen the ones on e-bay from coast rv awnings around the $1400. Just wondering if anyone has had any feed back on how good or bad they are, as it will be only something we use every now and again. They seem to be about $1000 cheaper than the others .Thanks for any advice, Barney
