That's competitive out here with the general competition, so I wonder why (profit aside) they think they can get away with it here, when we have less extreme temperatures.

Higher average running temp for air i take?

Nah

95+% are sealed road townies

There is generally an 'extreme' provision for outback driving

Asian manufacturers look firstly to succeed in the U.S. market and thus their penchant for the lots of stuff look.

I prefer European subtly and am probably regarded as a masochist for owning a frenchie
