About 10 years ago I bought a Chinese made tent off eBay, it had a brand which I can't remember, but it was identical to all the other branded Chinese tents that were being imported at the time. I went that way because the ARB/TJM etc tents were three times the price at least, up around $4000, more than I wanted to spend. I loved that tent. Had it permanently mounted to the top of a 150 Prado and used it heaps over the 4 years I owned that car. The tent was getting pretty tired by that time so I let it go with the car. It was quick and easy to set up/put away, it kept the rain out, was not very midgee proof, mainly all the gaps where the tent folds in half I think. The mattress was pretty crap, but I put up with it for a couple years and then replaced it with a 70mm high density foam from Clark rubber, much better. The floor sections underneath the mattress, some sort of alloy sandwich I think, cave in pretty easily if you get up to too much acrobatics in the night time, but the Clark mattress hid that pretty well.
A year or two ago, we bought a TJM Yulara rooftop tent as they are now significantly cheaper, we paid $1300. I'm buggered if I can pick any difference between this one and my old one, I would assume it's made in the same place my old one was. The mattress has already been replaced with the HD foam as I'm now 10 years older and get uncomfortable easier it seems, and the TJM mattress is just as crap as I remember my old one to be. All in all it's an OK tent, they're worth what you pay for them, but gee those mattresses are bad lol
Cheers,
Dave.
