We drove North to Tuk in July of 2018 and it was a most memorable experience. The South Canol Road is an absolute must, it was one of the most enjoyable sections and easily the most desolate road we drove on our entire adventure. I also really preferred the Cassiar Hwy over the Alaska Hwy, but it makes some sense to go up one way and back down the other. If time permits, a side trip to Stewart/Hyder and the Salmon Glacier while on the Cassiar Hwy is always worth checking out. I'd suggest spending a couple days in Dawson City, just park and play tourist. We camped in the campground right in town, and it allowed us to just walk around everywhere. Take an extra case of bottled water along, and offer it up to the cyclists you pass by while on The Dempster. We even ran into one poor guy who cycling who seriously under-estimated the water he required.
I'd also say to really take your time, drive slow, and enjoy the sights along the way. I found that even after 3 weeks, our trip was over before we knew it, and I wished I'd spent a little more time just smelling the roses. Oh yeah, and get a copy of The Bible.... I mean The Milepost. It's worth it 's weight in gold.
Enjoy.
