Just beginning to do homework

Thanks to all for your input. So the tour is probably out and will use the resources listed for further guidance. I should have been clearer about the timeframe to get out to AK. I was thinking 2-3 weeks each way to get out there and return. No way will I ever budget 300 mi.day to go anywhere. I do 350 max, but try to keep our daily mileage to 250 or less, depending on road conditions.
