Hi Craig,
We`ve had our Austrack tent for 18 months and can`t fault it. We camped in really bad weather at Kinchega, no problems whatsoever. Ours is the 12 ft. and we are going to put gas struts on to make it easier to put up but that`s the only thing we would change .We bought ours from Southern Cross Trailers at Penrith where Scott built the trailer.
I don`t know how to do the link but if you search Austrack Camper Tents there is some info.(may have to click on revise search).
Also on page 6 of My Camper Build under Austrack there are plenty of comments.
Good luck with your venture,
Robyn.
