I've done many trips from Ventura to Alaska and Arctic Canada and back. It's a great trip, though you'll likely find BC, Yukon and NWT up to Inuvik to be the best part of the entire trip. Suggestions: Take Cassair Hwy as opposed to the Alaskan Hwy, visit Hyder along the way. Don't miss the Yukon River bush town of Eagle, Alaska (I was married there), Dawson City Yukon (best food is at Klondike Kates), the Dempster Hwy to Inuvik. At Denali, I strongly recommend the inside campground of Teklanika Camp. You must reserve and agree to stay 4 days without leaving, but at this camp I have seen many grizzlies and wolves.
And if you end up in Anchorage the Bear's Tooth theater and brewery is a blast! Avoid the Seward Peninsula, it is very densely visited by RV's and the sort. Way too crowded.
Alaskan historical Audiobooks you might consider listening to on your long drive up: "Coming Into the Country" by John McPhee, "Jason's Gold" and "Down the River" by Will Hobbs and my absolute favorite, "Kabloona". I think all are available on iTunes.
Enjoy your trip. If you have more questions feel free to ask.
Wow! I will surely ask for more info. I really appreciate the tips. Right now, though, we are still working on the vehicle.
