Hi, I looked at them years ago when I was going through a similar exercise.
I am being a bit harsh here but its my honest opinion. I found them to be a bit dated in design, very basic, not very appealing to the eye and lacked features for the price. They are not too bad in build quality but once again very basic for the money.
The mechanic shop on the road to Mole Creek that does the rego checks builds the trailers for them if you ever wanted to have a sticky beak

As for the tent, once again I am being brutally honest in saying that I persb=nally think there are far better designs in the imported market as far erection goes and for better money. (sorry pete)
In saying that, Tassie is limited for places to buy reasonable camper trailers at the right price so they have a market down here.
Personally I would keep an eye out for a good second hand unit even if its on the mainland. You should get a well made trailer with features, using an aussie tent for around the same price.
