Gumb is your van a Pop top ?
No, ours is a 17'6 full height van. As per the the pic I posted previously.
Goldstream are made locally too, as are many of the others like Supreme, Coronet, Lotus, A van, New Age, Jayco, Coromal, Australian Off Road, the list goes on.
The fidges and hot water units are all imported as well as roof hatches, windows, air conditioners, microwaves, washing machines, towing hitches, led lights, TVs etc.
Wiring looms come with the battery management systems supplied again by outside companies like Redarc, BMP and Projecta.
Suspension is also supplied from outside the van factory (e.g Alko and Cruisemaster).
So vans are basically a hybrid of Aussie made (read assembled) and imported fittings with chassis often supplied by dedicated chassis makers.
Then it comes down to after sales support, longevity in the business and quality of construction. If you look at the interior design they are all basically the same, just different colours. There's not much you can different insdie a 17'6x8' box.
