There can be a significant difference in the build quality of products made in China, dependent on the input from the designer/vendor and also factory management and staff training.
I also believe that where the Chinese have an understanding of, and use some of the products they make is critical. They aspire to own an iPhone for instance, but no Chinese family ever has gone offorad in a camper.
The bolded part. You can by an imported "off road trailer" for under $10,000.00 (meaning hard floor rear fold), you can buy an imported "off road trailer" for $14,000.00 - $18,000.00 & there is a huge difference in quality. Wild Boar is not the only company that does them, there are two - three others in SE Qld I have seen. The only difference I can physically see would be the different material used on the tents etc., all the seals are the same as I've seen on locally made items, I have independent suspension on my Lifestyle & the one on the Wild Boar certainly looks as good. They are not light weight junk, I've picked one up to have a close look & was surprised at the weight & thickness of the steel. I have seen the drawbars before they are fitted to the chassis / subframe of the trailer, they were hot dipped gal and from memory 4mm steel, bigger & heavier than on my camper which I have taken on a few nasty tracks.
I'm not a welder or such, I'm a builder, so can't really comment too knowledgeably on the welding, but to me, it looks quite good, all welds look like they have penetrated as needed & are clean & tidy, the bits that the shockies attach to (the hangers?) are very solid (probably 10mm steel from memory) & so on. Like I say, I'm not a welder or engineer etc, but these campers in this price bracket certainly don't look like junk, & the paint job is just a bonus. I have looked at some of the top range campers, AOR, Swag, Kimberly, Cub & others, so I have been under a few over the years. The nearest I can come with an Ausie made camper to this price range is around $29,000.00 - $30,000.00, much cheaper than a few mentioned above, but still out of my reach, so next option is to look at imports.
I remember when Japanese gear was classed as rubbish. And yes, I know the time difference between then & now, but it didn't take long before a hell of a lot of people were driving Japanese vehicles & were quite happy to.
