I find this all very interesting. It makes me think that I've read it all before...
The concept of individual customisation is a good one and I see now that Pioneer Campers are offering a semblance of that. Also Lifestyle listened to customers like Theo who wanted more beds inside for kids or a dinette set-up and responded.
The concept of "imports v's local made" will fade over time. It does in any consumer product market.
Take bicycles... (a market that I'm involved with and know well since the 80's)
it used to be that the only "good" road bikes came from Italy (generalizing here ok) and the "good" mountain bikes were US made.
Brands like Intense, Turner, Santa Cruz and Ellsworth, used to stand proudly on their "made in the USA" heritage... well, currently... previously "MADE IN THE USA" stalwarts like Intense, Santa Cruz, Turner and Ellsworth are selling China made carbon frames now.
anyway... their selling features used to be things like suspension performance (cutting edge designs), quality of finish and the immortal "made in the USA" sticker on the frame.
Previously, I subscribed to this thinking too.
then I rode an Ibis Mojo. carbon. And made, with almost every single other carbon bicycle frame... in China. Oh lordy... that bike rode soooooo nice. it made me rethink my perception of where a bike is made, v's the manufacturer's quality controls and design ability. (social and human rights issues notwithstanding)
I mean, I can get online to Alibaba right now and find a carbon bicycle frame with "reasonably" well designed rear suspension design (copied off a more mainstream design) for around US$450... but a brand name frame will set me back $2k
The difference is what you don't see. The quality of the carbon weave itself, the quantity of resin used, the pressure used to form the frame and so on.
The point I'm making, is that with any product, you can go to China (for any product) and ask for "same but cheaper"... or you can give them a very detailed list of specifications and QC standards to adhere to... and they will give you a price.
I think, to date, a larger % of trailer imports may have been following the first option... but as time goes on, some of them will switch to the second method. And once they do this, their pricing will increase (or their margins will decrease). It may be only slightly... but it will increase.
The better and more specific your specs... the better the end product. And the more it will cost. Even from China.
To be honest... I'm utterly dumbfounded that no-one has straight up copied a Tvan out of China yet.
