I drove from Seattle all the way to Prudoe Bay about 4 years ago in my
Westy.  It was an awesome trip.  The only bad thing was the drive back. I
spent 2 months getting there, but only 10 days getting  back.  Anchorage to
Seattle is farther than Anchorage to Miami if I remember right.  I saw a
great bumper sticker on the way back.  It said "The Alcan, it is a great
drive, one way?"  What you are doing is the best way and the way I would do
it again.  Take the ferry up, and a great, long, camping trip on the way back.
