Brulaz, make sure you have a small vacuum cleaner along for the Dempster. When we did it in 2016 it was rainy/wet most of the way north. I power washed the back of the camper to allow us to get in at Eagle Plains, and again in Inuvik because of the mud on the camper and truck.
It was beautiful sunny days driving south. The dust is like flour, and it sucked in the door of the camper, being on the back. We spent an hour with the little dustbuster vac before we went to bed. The hardware store in Dawson City didn't have the baby Shop Vac in stock , but I got one in Whitehorse when we got there and vacuumed the whole camper.
Wet=mud
Dry=dust
Enjoy the north.
