I've had both import and local made.
I purchased a XXX (not an MDC) off road camper flogged by a magazine.
The tent was imported, but the trailer was made here, the trailer was the biggest POS I have ever seen. The tent was great.
I purchased a Lifestyle (I can't recall the model) when they had a batch imported to keep up with demand. It was a really good camper. It was built to their spec and had to meet their standards. It wasn't a generic import sold through different companies. I know own a Lifestyle Elite. Only because this is the only tent model they make now. I wanted their pov pack Southern Cross model. But they have stopped making them now.
We all drive 4wd's imported, our iPhones are imported.
I wouldn't piss on any Australian made car (I would like a 327 chev HK Manaro though), just because it's made here, doesn't mean quality. Look at new Jayco campers with their roofs collapsing at the moment. Aren't they made in Dandenong? A day doesn't go past without some poor dude on FB posting his/her new 2015 Jayco Hawk/Eagle/Swan/what ever with its roof on the piss.
If the camper meets your expectations, then go for it. Who gives a flying hoot where it's made.
Not everybody has $30k plus to spend on a tent sitting on a 7x5 box trailer.
