I have an add on room for an Australiawide annexe. We got this with our van but do not intend on using it. I'm really not sure how much it's worth so am open to (reasonable) offers. Located in Attadale WA
I have a 30 second tent and when I went to the Australiawide Annexe stand at the show they said they could make up a adapter for it.
Might be worth a look (heaps quicker to set up and much more sturdy)
