We've run the drive to AK from Delaware in 06, 07, 09, 11, 13, and 15. We visit with friends in Duluth and then go without sightseeing. We plan 10 driving days total, 5000+ miles from Delaware, but last year we started late so we pushed and made Tok in 7 drive days. Our route after Duluth is US 2 to I-15 (Shelby MT) north to a bypass around Edmonton, northwest to Grand Prairie, AB, then Dawson Creek BC and the Alaska Highway to Tok, AK. We do not stop at any RV parks but boondock all the way. We do refuel at the larger cities as the out of town fuel stops are expensive. We can easily run 600-650 miles a day until we start to get north of Whitehorse where the frost heaves and road repairs begin to slow us down. Be sure you get a copy of the MILEPOST. Just about every turnout and wide spot in the road is in there, so overnights are easy to select. As someone mentioned some turnouts are posted NO OVERNIGHTS, but we've never been told to move on. However, we don't pick the scenic or developed ones. When you hit Tok you may want to stop in a park to get the rig washed and do clothes washing. The northern end of the Alaska highway can be dirty or muddy (construction) and a cleanup is advised. From Tok take the Tok cutoff over to the Richardson Highway, then the Glenn highway from Glennallen to Anchorage. I'd plan to stop north or south of Anchorage as the Kenai run may have heavy traffic if the salmon are running in the Kenai and Russian rivers.
Once past Edmonton, a number of towns have free dunp sites and free water. You need to ask when refueling or check closely in the Milepost.
If you decide to run this route or close to it and need more info on things like overnight sites in Red Deer, the bypass around Edmonton or overnighting in Grand Prairie, just ask.
