What to plan for if you're thinking the Al-Can Hwy in a TC?

We went to Alaska 3 years ago, may June no bugs we did not do the Alcan but we did the dempster to the artic circle instead mostly all gravel, go slow and pull over for large vehicles especially those going fast this may help prevent the window loss or light loss. Good luck, we camped free on the whole trip wherever except in town.
