Re Dalton Hwy. We have made the trip 3 times.
In 2005 drove our 36' motorhome (gas) as far as Marion Campground; that is 5 miles north of Coldfoot, and parked it. Took the pickup to Prudhoe Bay.
In 2009 left our motorhome in Fairbanks and drove the pickup to Prudhoe Bay. Spent the night going and returning in a B&B in Wiseman. That is about 20 miles north of Coldfoot.
In 2013 drove our 40' motorhome (diesel) as far as Marion Campground and parked it. Took the pickup to Prudhoe Bay.
You can see our trip log at the website in my signature if you are interested in my comments about the road.
