It's a great idea, but why not spent the two months cruising around Vancouver Island and the central and southern interior of our province, then back to California? In two months you can enjoy yourselves and travel at a reasonable pace, or drive yourselves crazy with your kids and adults in long daily drives at much higher expense. If you find it works well, plan it again but add a month to enjoy it longer.

One nice thing with a motor home, which you loose in a travel trailer, is access to the fridge, TV, bathroom, and toys while under way. While I agree with previous posters about the flexibility a separate TV and TT offer for multiple-day stays at a campground, for a trip as long as CA to AK, you are going to have a lot more "travel all day, stop for the night, and travel all the next day as well" sequences.
Plus; for something which will probably incur me the wrath of those with an absolute approach to safety; with a motor home, you have the option of piling the kids into a bunk and driving several hours before they wake up, for those occasional long days.
For your planning purposes, once you hit the north, don't plan on doing much more than 250-300 miles per day--particularly with kids along for the ride.
People make the trip up here in all kinds of vehicles. With long hours of daylight and no need for air conditioning, you'll probably find that you spend more time outdoors when camped up here, than you might in other locations. So, your living quarters are more for cooking and sleeping, rather than where the family will spend all day while camped.
The best idea is to just go. When we lived on Vancouver Island, we vacationed every year possible in Yukon & Alaska. First year in a tent, then truck campers, then Class C, then fifth wheels. Every trip was enjoyable.
Some trips were only three weeks, some were two months. Didn't matter.
Find the set-up that works for you and your family, then do the trip!
BTW, after more than a dozen trips north, we now live in the Yukon. Love it!
will add ... the advantage to a van and trailer is more flexibility. Some of your clan may not want to explore some days and will prefer to stay at the campsite with the trailer, while the others head out for a while. Not everyone needs to do everything together.
As well, you won't need to move the whole household everytime you need to run an errand.
Van and trailer are a good choice; any RV is a good choice for the north. Many folks in Yukon have travel trailers for their family travels.
