We flew back just 2 weeks ago from Whitehorse. We rented a new class C in Elkhart and drove up. Most of the advice above is good, but I will add a few things.
For the 5er, an extra spare tire would be good. Make sure, the hubs are packed when the switch is made to the new wheels. Have a spare wheel bearing, race and seals, already packed and ready to go. Put the bearings and races right in a can of grease. Know how to replace the wheel bearing and bring the tools and rags.
Watch for soft shoulders on the roads. Slow down if you see little orange cones along the road. I thought the frost heave was going to throw me through the roof of the pickup the first time I hit a frost heave. I thought a little cone marked a little problem. Wrong.
