Shouldn't be a problem if you take it slow down a bit and enjoy the trip.
Took this road on Harley Touring bikes a few years ago with a buddy. We certainly weren't travelling all that slow but we did stop to enjoy some of the scenery. We left Whitehorse about 9am after a morning coffee, stopped at Twin Lakes (I think) for the largest cinnamon bun I have seen in my life and on to Dawson where we spent about 3 hours looking around. We were going to have a sour toe cocktail, but they wouldn't serve one before 8pm. So at around 4pm we took the ferry and headed towards Chicken. Locals told us it was originally named Ptarmigan but when asked to spell it for the new Post Office they decided Chicken was easier. We carried on back towards Haines Junction, and finally stopped in Destruction bay after we lost our light around midnight. We grabbed a room and headed for Whitehorse in the morning. I hope to recreate the trip someday, but leave earlier from Whitehorse and do the same route, arriving back in Whitehorse on the same day. Crazy, I know.
Anyway, we passed lots of trucks, RV's etc on the way. I also plan to take my dear wife and the motorhome to do TOW highway, but plan on lots of stops.
Do stop and get a passport stamp at Poker Creek Border crossing, probably the coolest one I ever got
