rv to alaska----- campground reservations

We only made a couple of reservations. One was for Denali as we have a big rig and we also made a reservation in Homer but we decided to stay longer and we had to move to another camoground d and we did not make reservations there. We did not make any reservations on the Canada portion of our trip. Only once did we get to a campground and it was full and that was in Dawson Creek. We just found another campground in the area and all was fine. We stayed at a variety of campgrounds: military, Canadian govt, BLM, USFS, natl parks, and commercial. We also dry camped in a couple of commercial campgrounds for a lot less money. We even stayed in a turnout on the Alaska Highway. The first time, no one even came into the turnout while we were there (about 18 hours) and on the return trip, a truck and another RV stopped for a short period right after we arrived and again, no one else came into the turnout. We felt perfectly safe. If you have military privileges, you will be very happy to use the Commissaries as grocery prices are much like those in the lower 48. Had a great time. Driving more than a couple hundred miles a day will be very tiring. It took us 2 weeks to get to Dawson Creek, BC from the border since we did not travel every day. The long daylight hours lull people into driving much longer than they should.
