While I'm at it we just got back from lederville which is just south of drake and is a cattle property on the rocky river road in northern nsw. I found it on wiki camps but he does have a website. Beautiful! place and the kids had a ball.
Quick question for you mate. I have a camper trailer and use an awning and room the same as you for a shower. Have just got an expanda and was planning on putting it on the side just as you have done, how did you mount it to the wall of the van?
