John, The Dempster hwy runs from Dawson city to Inuvik in Canada
crossing over the Arctic circle, The haul road is the Dalton hwy it
starts just north of Fairbanks and runs to Deadhorse up by Prudhoe bay,
You would have to leave the trailer behind if you take either hwy all
the way up. The 4runner is a good rig for driving up though. UD
