Dolly, Flat Tow or Trailer best way to Alaska

We come up every 2 years. 06, 07, 09, 11, 13, 15, and we're now sitting in Valdez shrimping. We've brought 2 brand new coaches up (a 2008 Allegro Bus and a 2013 Allegro Bus) and have not had a problem. North of Whitehorse the frost heaves can get bad but the trick is to slow down and use the whole road when opposing traffic allows. The area north of Destruction Bay in YT and north of Beaver Creek in YT to the border were the worse, but you also need to watch the border to Tok, AK. Again, slow down and watch for signs, flags and cones marking the worse sections. These are not 55mph roads, but 30-40 is realistic in all but the worse places. Besides, there's too much to see. Slow down and enjoy. If you do get a stone chip in a windshield, just get it fixed in the next big town. Don't let that deter you from coming up. Just beware---the place is addicting. We pull the full size pickup but we need the space for the freezer, boat, motor and fishing gear. We pull with a full cover on the truck (Coastline Cover)
