In 2006 we purchased an Oz tent RV4 and had 2 of them replaced under warranty due to being stitched incorrectly and leaked in the rain.
We also found that when we got into cold temperatures the condensation inside on the roof was unbelievable "unless" the optional fly was fitted.
When the second Oz tent went back under warranty we asked for a full refund which to there credit they did.
We then purchased a Southern cross touring tent (ultimate 11) and have not looked back since, great for short trips when moving every day.
It fits the wife, myself and three kids with room for our bags as well. Doesn't leak or condensate is quick to erect and pack up and the finishing with canvas and stitching is top class.
The mattresses we chose were the Thermarest self Inflating matts they have also been fantastic and roll up very compact, we have had these for 4 years now and they replaced our old air beds.
In saying all of this the Mrs and I said we would never buy a camper trailer but we have currently placed an order on one for the big lap planned in 2014, so It will be interesting to see If the trailer then goes on our smaller trips and replaces our current set up???
Hope some of this helps
Cheers
