From my experience so far, there are a whole multitude of quality differences in imported campers.
Some are pretty good (Ecomate

) some are horrid.
The best thing to do is look at a few, set the main tent up on them and see what they are like.
Go right over them, check how well they are put together. It will be pretty obvious if they aren't done well.
Take your time when looking and work out what you need in a camper and what you want to spend and how you intend on using it.
There are some great bargains to be had second hand, but there are still some pretty good imported campers around.
I've noticed some people seem to put all imported campers in the same basket, but to me that is like putting a great wall ute into the same basket as a hilux. They are both imported, but one is certainly better built than the other. (My opinion only lol)
I got into working for Ecomate because I was surprised at the quality for a mainly imported camper.
But what tipped me over was Kerry's (the owner) attitude about how they get put together and what parts are used.
Are they the same as a kk? No, but they meet a different price point in the market.
That's my two cents and is worth what you paid for it. (Nothing lol)
But most importantly, good luck mate and no matter what you end up with I'm sure you will love getting out there and enjoying it.
Cheers
