Since the days of the Klondike gold rush the transportation of goods to Alaska has been required to pass through the Port of Seattle/Tacoma. A legalized form of taxes levied on Alaska that the city of Seattle got the federal government to make into law back then.

So for the most part all vehicles came from the main land US factories and passed through the Ports of Seattle/Tacoma before heading to their final destination in Alaska.

Another way vehicles made their way to Alaska was via fishing boats. The majority of Alaskan fishing vessels spend the off season in Puget Sound where they get maintenance performed. To help offset those costs fishermen will load their boat up with all new vehicles they can fit then sell them for a profit. And sell them for less than a local Alaskan dealership could sell it for.

I've seen boats depart for Alaska with a dozen or more new trucks lashed down on deck.

Finding a truck coming from a Kent Washington dealership in Alaska is perfectly logical. I'd bet it was probably sold as part of a package deal with 3 or more trucks.
