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

I went to Alaska back in August of 1992, I didn't run into mosquitos at all. I went from Dawson Creek to Delta Junction then down the George Parks Highway past Denali to Anchorage, At Tok Junction we went south down the Stewart-Cassiar Highway. That highway at that time was only about 1/2 paved and 1/2 gravel topped. It doesn't seem like 22 years have passed, I need to go visit again.
