For Canada in the winter I would run 5-30 oil.

I would also take an emergency pack of food and water in case you get stranded somewhere. I would also take along a bunch of phone numbers you can call if you get in trouble.

I might ditch the jumper cable and buy a booster pac battery.

Some pillows for when you have to sleep in the truck.

By the way, your trip sounds awesome! Too old and tied down with wife,2 kids but maybe someday I will get to do one of these trips. <img src="/forums/images/graemlins/cheers.gif" alt="" />
