We are almost home from spending 3 months in Ak. In drove the Alcan on the way up. and the Cassiar on the way back. IMHO there is no reason to take the Alcan unless you just want to say you did it. I think the Cassiar is much nicer road and prettier, how ever if I do it again I will take the ferry from Bellingham to Haines and then The Cassiar back! With a TC the cost wouldn't be that much more than fuel in BC and Yukon and you could make it in about half the time and wouldn't have to hassle with the road. I'll probably catch flak for that but that's just my opinion. Fuel is not much different in Ak and Wa. I think the cheapest diesel I found was $135.9 per liter. Most is ~ $147.9.You can do the conversion.
There are many pullouts in Ak and you can overnite in any as long as it's not posted. Few are. But in BC and YT most are.They want you to spend your $ in the campgrounds.Food is a little expensive in Ak. but eating out is very expensive. Same for Canada. They say eating out is expensive because every thing is shipped in. But food in the grocery store is shipped in also and it's not near as bad as eating out.
Roads in Ak are not any worse than the lower 48. In a lot of cases better unless you start going off-roading. This is a great trip, do it and have fun!!!
I would go in Aug & Sept. or Oct, to miss the mosquitos and see the fall colors.
