Interesting discussion. I agree with many of the comments here. I myself contacted AT about 5 years ago looking at the idea of importing a Chaser. I liked it because it was different to what we have here and I was seduced by the shape and look. I didn't as it just wasn't worth the dollars after importing. To be honest, and this is no disrespect to AT, I'm glad I didn't as I now know better what I want out of a trailer and the Chaser just wouldn't have done it. I actually now prefer the Horizon over the Chaser as the available space is much better utilized. The layout is still not what I want and the small tents don't suit a larger family.
As Apsilon said there are heaps of options around locally IF you go looking for them. Certainly the most common, and budget oriented design, is the typical side fold big canvas tent. They do take a while to set up and take down but when you are on a budget, something has to give. Many of the rear folds, such as the KK are brilliant on setup time if only for a quick stopover and as Brad (Tucson TR4) can attest they can be added to to make a tent city! :Wow1: The Tvan also sets up in a couple of minutes.
As I've now got 3 young kids, set up time is crucial and we want beds, beds, beds. We can't get away for extended periods but are planning on a month next year in Tassie. We ended up buying a Jayco Dove Outback and are loving it as it just suits our needs CURRENTLY. In the 5 months we've had it we get away for a long weekend every month at least and that's the best thing you can hope for. I know it's not expedition material but in reality a true off track expedition isn't going to happen frequently or soon.
It's true that many new players just make the same as the others do and no doubt the weak won't make it. Those who improve their designs and product will. I'd also say that the majority of camper trailer purchasers are "non-thinkers" and just buy what's "normal" and are happy with it. Those who engage in this forum are "thinkers" and in the minority. I still have intentions to build my own design and hopefully it'll be a true offroad beasty with quick setup and everything where I want it.
Camper Trailer Australia Magazine do some great reviews and rate all campers on setup times, bushability, family friendliness, and other things. Worth chasing down if you want to find some variety and know what suits your needs.
