Hi Monte
Tom has given you the straight scoop. Advice from friends who have made the trip 27 times "go slow". Enjoy the trip, the roads that aren't being worked on are good except the Alaska roads are prone to frost heaves in areas that really require caution. I drove from Boise,ID to Anchorage in 5 days to get there for Memorial Day.( My son was in the Airforce and thats when he had off. ) It was a forced march and I would not do it again.
One thing you need to remember is that the days get longer as you drive north and you will be driving in daylight 22to23hrs a day. So it is possible to drive for 4-5hrs, take a nap, visit a hot springs,shop, eat and drive on till your ready to stop at your next destination. I don't want to encourage you to do high miles, but to give you an idea of how you might have a relaxing trip. I did two 400 mile days and I did not want to get behind the wheel for the next one.
I would go to Alaska first through Alberta and look at California on the return trip. I don't know your interests but our trip diary filled a book. Speaking of books, have your copilot read the Mile Post to you as go and look ahead for sights to see so you can focus on avoiding the moose,bears,deer,sheep,eagles that inhabit that country.
Be Well, Jack
