Yes i purchased one an SC1. We use it on the back of our OKA
Not bad for the price but there are a few things i didn't like. The canvas wasent installed the best and is hard to close the windows when open.
The seams leak inside when it rains in a few areas. Working on fixing that with some wax
Some of the workmanship is really rough and looks slapped together, the fridge slides are very tight for an engle fridge and cant be used with the cover on. The Kitchen door latch is hard to use and just cheap Shit.
The welding on the adjustable legs is crap i ended up re welding some of them.
Considering what some others charge its not too bad if you are handy and can fix a few things yourself. They have a warrenty but i couldent be botherd going through the hassel of chasing it up. I have made a lot of mods including fitting an upright 40L Engle at the back, a heap of electrical work and other stuff. It is handy because it comes off without too much trouble although i am working on a 4 Hydraulic ram system.
Your best bet is to go and look at one in a show room, in Perth it is west coast campers.
Goodluck
