I will be buying a new Tundra Double Cab 4WD in the next couple of months, but, living in Canada's North, I am concerned that it comes with a cheap-feeling sliding rear window (what on earth for??) but not a defroster unless I buy the 'Limited' edition (forget that - $$$).

I'd like to hear from owners living with the defroster-less '07 Tundra in winter. And I'm wondering if a defroster will be an option, sans the sliding window, for 2008.

Thanks, all,
