Global caravans

Brecath - The problems with American vans is that they are not built to the same standards as Australian vans. They're not built to handle our rough roads. They crack up under Australian road conditions.

They're not built to Australian standards as far as door widths, types of fittings, and accessories - you know, all those things that break, and need replacing!
Their electrical fittings are all different. Windows, hinges, door locks, they're all American brands, known as Unobtainium.
Their plumbing uses NPT threads, not BSP. Ever tried to get NPT pipe fittings? I've got about 50 boxes of them, in Nylon, and I'm probably the only bloke in Australia with them.

The American vans are built from American softwoods. Some of these woods have a lovely finish for cupboard facias - but using American softwoods in caravan frames is a recipe for future disaster.
The wood can't cope with our severe climatic conditions. It breaks and splits and lets water in.
The materials used in American vans have poor UV resistance, because everything in North America is centred around a climate where 20°C is a hot day.
They build caravans to cope with -30°C temperatures. We need vans that can handle 50°C temperatures. The Americans barely understand what the hot dry Australian cliimate does to materials - or what is needed in our climate.

There are numbers of American vans and motorhomes that have been imported privately, and I wouldn't touch any of them with a 3M barge pole. When I see an American van that has been produced for Australia - after the company management have been to Australia, and done extensive road testing over a period here - only then, I would consider owning one.
Just my .02c worth for today - and I don't own an American van - but I have friends who have owned them.

Cheers - Ron.
