here's the page on the modifications we made (might be formatted a bit weird on a widescreen monitor)http://users.tpg.com.au/nlandgl/camperm ... rmods.html
Overall, we are happy with it. Had a few little problems (plus the winch which was a big problem, thankfully my father in law is a farmer and can fix anything!) but structuraly it's still 100%. After 100 nights and 21,000 K which included some very rough roads, it's still looks (and smells!) like new.
I took it back to Goldstream to get the winch rechecked and they decided to replace it and repaired the hole we cut to get at the winch. They fixed the 12V outlet which they thought must have been done by the dealer as they agreed with me that it would never have worked how it was wired up and they had no documentation about it. They also fixed the fridge surround which I'd broken myself without being asked (they actually had to order in the part). Customer service at the factory (we're about 45mins away) was very good.
