Vancouver to Whitehorse via Vancouver Island?

Thanks for the links. Yeah, fuel can be an issue. Last year we went from Banff to Revelstoke. I didn't fuel up as per my usual routine since my fuel guestimator showed more than adequate miles remaining till empty. Well, I was getting very nervous before we finally got to our destination, as the fuel gauge got close to E. Lesson learned.

This trip just may be the excuse I've been looking for to install an auxillary diesel tank in the bed under the cover. An extra 40 gal or so would go a long ways when you're far from fuel.

Here's a couple of websites that might help.

There are a few stretches of Hwy 97 (Alaska Hwy) on your return trip that may push your fuel supply/reserve a bit. Check some distances on Google maps for examples.
I used gas when I was up there in 2016, and there is fuel available, but some of it's stored a bit differently than at normal gas stations. They have these what I called "fuel dumps", huge tanks that contain gasoline and presumably diesel, although I wasn't looking for diesel last time out, that are pretty much self serve, and they do take credit cards, and cash iirc, but you'll see what I mean when you get there. One thing that's going to be different, is hours of operation. Not everything (perhaps very little?) is open 24 hours a day, so plan accordingly.
