Drove Edmonton, Alberta to Vancouver, British Columbia (a little under 800 miles), in an average of -22 (C), in a Nissan Armada (5.7l V8 with Superchip) in a little over 14 hours (and $600 in fuel!
)...
Other than tyres, oil levels and wiper blades (essential for flurries), we pretty much packed & left. Couple of bottles and snacks, plus numerous bathroom breaks and stretch-stops (I have a spinal injury, so these were needed!)
The only thing I would say is don't forget your sunglasses - especially in winter. The low sun, when it makes a rare appearance, can really screw up your momentum!
