I'll chime in here, I got a roof top tent from an ebay company last week that came with an awning, I already have an ARB so I gave it to a mate, I have to say its every bit as good quality as the ARB one, you'd swear they were made in the same factory! (ARB say they aren't).
I'd have to assume the Tigerz was the same, personally I recon theres a factory in china the size of Tassie pumping them out for a couple of bucks and selling the same product to everyone.
Only reason I didn't get the Tigerz tent was cos a the place I bought from was in Sydney (so no freight) & I was able to view it. Otherwise it would have been a Tigerz roof top for sure
