As someone pointed out on the ADV Rider forum

44 Days – we also had free lodging in Anchorage for 4 nights so that brings us down to actually 40 days of riding.

Gas and Lodging

$2447 + $1664 = $4111 / 44 days =$93.43 per day / 2 people = $46.71 a day per person

And to add

Groceries, including food, snacks, beer etc…

About $900

Ferries, flight over McKinley and other side track adventures

About $1000

Total for 2 of us

$6000 approximately
