Save your money on the All Terrains. With the Dually it won't make much difference in mud anyhow. You already have chains, as long as you know how to put them on that will solve any problems of wet roads. The Chin is a pretty good road, it has to get really wet before you will need chains. They run all manner of heavy trucks on it year round, most do not have 4x4 and even loaded semis rarely need to chain up unless it gets really icy.
Given the time of year, I would come up through Sask to save time, go back through Montana for variety and scenery. Hope you have a great trip.
