We took that trip in a class A. Will do it again this summer. Didn't need a spare last trip and don't feel a need for it this year. Highways are paved - except for numerous repair areas of winter damage - just take it slow through those spots.
However, we left our Berk in Fairbanks and took our Jeep toad up the Dalton Hwy to Prudhoe Bay, but with 2 spares. Wouldn't want to be caught on that road with flat tires.
FWIW, I don't think I've ever noticed a class A anywhere with a spare tire.
