We are currently in Fairbanks area and are considering driving up the Dalton Highway to maybe Coldfoot. Towing a 5th wheel and looking for any info on this stretch of road.
Go to the Morris Thompson Cultural and Visitors Center, and ask someone there to give you a picture of what you'll encounter on the Dalton (Haul Road) Highway. They're pretty knowledgeable about the environment. Or, ask a State Trooper for an opinion.
